WalkthroughAdded a macOS-only fullscreen Escape guard that replays intercepted events. Integrated the guard into root-window and server-view input handling. Added automated tests and a manual QA pack covering macOS behavior and Windows/Linux regressions. ChangesFullscreen Escape handling
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to On macOS, the fullscreen Escape guard has a narrow deadline-boundary case that could allow one Escape event to reach native fullscreen handling unexpectedly. The PR is otherwise mergeable, but the owner should address or explicitly accept this bounded behavior risk. Sequence Diagram(s)sequenceDiagram

|
|
||
| - Comparison range: `master` (`7aa3dae6d`) to `fix/macos-escape-exits-fullscreen` | ||
| (`3bdd1e747`). | ||
| - Changed surface: Electron main process keyboard handling for server webviews | ||
| and the root window (`src/ui/main/escapeFullscreenGuard.ts`, | ||
| `src/ui/main/serverView/index.ts`, `src/ui/main/rootWindow.ts`). | ||
| - User-visible risk: A customer watching a video in a fullscreen app window | ||
| presses Escape to leave the video and the whole app drops out of macOS | ||
| fullscreen, losing their window arrangement and Space. | ||
| - Hypothesis: With the app window in macOS native fullscreen and a video in HTML5 | ||
| fullscreen, one Escape press returns the video to its inline size and the app | ||
| window is still fullscreen, matching Google Chrome. | ||
| - Smallest useful proof: OS-level repro on macOS hardware. The Jest suite covers | ||
| the desktop wiring only | ||
| (`src/ui/main/escapeFullscreenGuard.main.spec.ts`, | ||
| `src/ui/main/serverView/index.spec.ts`), because a test generated key event is | ||

Do not replace native fullscreen with maximized state.
maximize is not native fullscreen. If F11 is unavailable, this step does not test the native-fullscreen path. Use a verified native-fullscreen control, or mark that check as blocked and keep maximized-window coverage separate.
As per coding guidelines, each branch-specific hypothesis must use the smallest useful proof.

Nice find on the AppKit redispatch root cause — the write-up made this easy to review, and the guard approach is the right shape. I reviewed the branch in depth and pushed 977e7fb with hardening for the replay bookkeeping, all behavior-preserving except one deliberate delta noted below:
- Auto-repeat leak: the replay credit was a bare counter, so a held ESC (auto-repeat ~33ms) could race an in-flight replay — the repeat got consumed as the replay, passed unprevented to AppKit, and exited fullscreen. Repeats are now swallowed without replaying (only the initial press is replayed). Deliberate delta: the page no longer receives ESC auto-repeats while in native fullscreen. This also dedupes the per-repeat
exitFullscreenexecuteJavaScriptcalls in the HTML5-fullscreen branch. - Stale credit: a replay landing after fullscreen ended (exited by another route) left the credit armed, so the next real ESC within the window leaked. The replay check now runs before the fullscreen gate.
- Simplifications: counter+expiry collapsed to a single expiry timestamp (the counter could never exceed 1); shared
isWindowInAnyFullscreenpredicate extracted so serverView and rootWindow can't drift apart; the serverView Escape comment rewritten (it described the opposite of the branch); debug log kept in packaged builds; guest→root forward bails on a destroyed root window. - Specs: auto-repeat swallow, non-fullscreen pass-through, and stale-credit clearing are covered. 47/47 across the three touched specs, tsc and eslint clean.
A few things I noted but did not change — mostly needing macOS runtime verification or a scope call, so flagging rather than touching:
- Cross-origin HTML5 fullscreen (
serverView/index.ts, HTML5-fullscreen branch): the branch preventDefaults ESC and relies on a fire-and-forget top-framedocument.exitFullscreen(). If fullscreen is owned by a cross-origin iframe (YouTube/Jitsi embed), that call may not unwind it, and since the keydown never reaches the page, ESC has no effect in that state. Worth a runtime check with an embedded player; a fallback (e.g. bail out of the swallow whenexitFullscreenrejects) may be needed. - Pointer lock: while the guard swallows ESC in native fullscreen, Chromium's browser-side ESC handling (pointer-lock release) sees neither the raw event nor the synthetic replay. A page holding pointer lock in fullscreen would be keyboard-inescapable. Needs a runtime repro to confirm.
- Replay after expiry: if a replay round-trip ever exceeds the 250ms window (renderer under heavy load), the synthetic ESC is treated as a fresh press and re-swallowed/re-replayed. Low likelihood, but there's no deterministic replay marker — worth checking whether
sendInputEventmodifiers survive intobefore-input-eventon macOS, which would allow tagging replays instead of timing them. - Two guards, three hops: a guest ESC is swallowed/replayed by the guest guard, forwarded to the root webContents, then swallowed/replayed again by the root guard. It works, but one keypress flows through two independent credit machines — a single-owner design would be easier to reason about if this area gets touched again.
- ESC keyup is no longer forwarded to the root window on any platform. All current root-renderer ESC consumers are keydown-only so this is fine today, but the assumption is only enforced by a comment.
The AppKit-facing behavior itself still needs the hardware pass — qa/macos-fullscreen-escape/ flows 01–03 should be re-run on the amended branch.

Expire the replay credit at its deadline.
Line 68 accepts a credit when now() === replayExpiresAt. A native Escape at exactly the 250 ms deadline can consume the credit and pass through to AppKit. Treat the deadline as expired when the values are equal. Add a test for the exact deadline.

On macOS, Electron hands every key event the web content did not consume back to the native window (`WebContents::PlatformHandleKeyboardEvent` calls `[ns_event.window redispatchKeyEvent:]`). AppKit answers ESC with `cancelOperation:`, which leaves native fullscreen. So pressing ESC while a video is in HTML5 fullscreen — or with nothing at all to dismiss — also dropped the app out of fullscreen. Chrome never returns the raw NSEvent to AppKit and therefore stays fullscreen. The previous guard only stopped forwarding ESC through `sendInputEvent`, which produces a synthetic event that can never reach AppKit, so the redispatch was left untouched. Swallow the ESC key down in `before-input-event`, which runs before the renderer and thus before the redispatch, and replay it with `sendInputEvent`: the replay still reaches the page but carries no NSEvent. While the guest is in HTML5 fullscreen the key is consumed and the fullscreen exit is driven explicitly, so ESC leaves only the video fullscreen, like Chrome. The guard is applied to both the server views and the root window contents, and is inert outside macOS. Also stop forwarding the ESC key up to the root window: only key down is consumed there, and the key up leaked an unguarded ESC once the guest had left HTML5 fullscreen.
Add regression coverage for the Escape handling that keeps the window in macOS native fullscreen. Automated coverage, in `src/ui/main/rootWindow.spec.ts`, asserts that the `before-input-event` listener is installed on the root window contents, that an Escape key down in fullscreen is cancelled and replayed, that the replay passes through, and that the handler is inert when the window is not fullscreen or the platform is not macOS. QA coverage, in `qa/macos-fullscreen-escape/`, covers the half no Jest test can reach: the bug depends on how AppKit reacts to a real key event from the operating system, and any test generated key event is synthetic and never gets there, which is what let the earlier regression pass CI. The pack covers video HTML5 fullscreen for both an attachment and an embedded cross-origin player, plain Escape with nothing to dismiss, the Escape/menu-shortcut/fullscreen-toggle regressions, and a Windows and Linux unchanged-behavior check. Also restrict the HTML5 fullscreen Escape branch in the server view to macOS. It was running on every platform, which changed Windows and Linux behavior for a bug that only exists on macOS; those platforms keep leaving the fullscreen exit to Chromium and keep the original no-forward guard.
- swallow auto-repeated ESC keydowns instead of replaying them, so a held ESC can never race an in-flight replay and leak to AppKit (also dedupes the per-repeat exitFullscreen executeJavaScript calls) - consume the replay credit before the fullscreen gate, so a replay landing after fullscreen ended clears the credit instead of leaving it armed for the next real press - collapse the pending-replay counter + expiry pair into a single expiry timestamp (the counter could never exceed 1) - extract isWindowInAnyFullscreen so serverView and rootWindow share one fullscreen predicate; restore the typed createInput fixture - bail the guest-to-root ESC forward when the root window or its webContents is destroyed - rewrite the serverView Escape branch comment that described the opposite of the code; keep the guard debug log in packaged builds - cover auto-repeat swallow, non-fullscreen pass-through and stale-credit clearing with new specs

Problem
On macOS, with the app window in native fullscreen, pressing ESC took the window
out of fullscreen. The most visible case is a video in HTML5 fullscreen: one ESC
press was expected to leave only the video fullscreen, but it dropped the whole
app out of fullscreen. It also happens with no video at all, when ESC has nothing
to dismiss. Google Chrome does not behave this way.
Cause
On macOS, Electron hands every key event the web content did not consume back to
the native window:
WebContents::PlatformHandleKeyboardEventinelectron_api_web_contents_mac.mmcalls[ns_event.window redispatchKeyEvent:].AppKit answers ESC with
cancelOperation:, which leaves native fullscreen on afullscreen window. Chrome never returns the raw
NSEventto AppKit, so it staysfullscreen.
The non-macOS implementation of that function only runs registered window
accelerators, and there is no ESC accelerator in this app, which is why the bug
is macOS-only.
PR #3270 addressed a different mechanism: it stopped forwarding ESC to the root
window through
sendInputEvent. That produces a synthetic event, which carriesno
NSEventand can never reach AppKit, so the redispatch was left untouched.Change
before-input-eventruns before the renderer sees the event, so cancelling itthere also cancels the redispatch. That is the interception point used here.
src/ui/main/escapeFullscreenGuard.ts: on macOS, while the window is innative fullscreen, an ESC key down is cancelled and replayed through
sendInputEvent. The replay still reaches the page, but carries noNSEventand cannot reach AppKit. A pending-replay counter with a short deadline
recognises the replay and re-arms if one is ever dropped. Only key down is
guarded, since
cancelOperation:comes from key-down interpretation.src/ui/main/serverView/index.ts: while the guest is in HTML5 fullscreen, ESCis consumed and the fullscreen exit is driven explicitly with
document.exitFullscreen()on the guest main frame, which also covers afullscreen element inside a nested or cross-origin frame. Otherwise the guard
replays the key.

QA
No Jest test can prove the fix, because the bug depends on how AppKit reacts to a
real key event from the operating system, and a test generated key event is
synthetic and never gets there. That is what let the earlier regression pass CI.
