Agent chat: a video's Open in tab and Expand each take their own click by teamleaderleo · Pull Request #24472 · manaflow-ai/cmux

teamleaderleo · 2026-10-23T05:07:34Z

A video’s Open in tab and Expand controls now have separate 28 px click targets, an 8 px gap, and a margin that absorbs near misses instead of playing the poster. On videos shorter than 126 px, both actions sit in a reserved row above the player. Normal and tall videos keep the existing corner placement, clear of native playback controls.

Leo (2026-10-22, relayed by claude-sr2), with Lawrence’s screenshots: “the thing i had in the henlo chat was just pasting some images lawrence said”. Lawrence’s caption: “trying to click between the two of them”.

The prior reviewed head put playing actions at y=45–73 px, which overlaps a 100 px video’s native bottom bar. The short-video row is reserved before playback, so starting playback does not move the video. One ResizeObserver watches only this video and disconnects on unmount or media-kind change. No animation loop, timer, or transcript scan was added.

Design reference: Claude’s apps/claude/live/image-viewer-masonry-layout.png in manaflow-ai/cmux-design-references, retaining quiet media surfaces and small hover controls. Existing glass and icons are unchanged.

Before / after

Actual gallery captures from agent-pane.inline-media, Chromium, 420 px, dark and light. Before is 11eaf48; after is d065c37. Normal and poster states are included to show they keep their existing layout.

Verification

Focused command: CMUX_BROWSER_TESTS=1 bun test test/inline-video-controls-browser.test.ts.

Red at b2ce227, hosted 40483541593: 24 pass/4 fail. Both engines reproduce the 100 px playing overlap and resize failure.
Final head d065c37, hosted 40486364338: 28 browser tests pass in Chromium/WebKit; 2719-file typecheck and scoped format/lint pass; all 12 before/after gallery cases are ready and their plays pass. Captured 32 PNG/step images, each decoded with SHA256 and PIL verification.
96 related inline-media tests pass in hosted 40484125645 at e2eafed, whose production files are identical. That combined run later failed in the old gallery fixture; the final run fixes its setup boundary.

Observed / Not run

The browser cases cover near misses, 100/180/280 px videos, resizing, actual separate Open in tab/Expand effects, and identical frame bounds before/after Play. Native app playback was not run; the runtime evidence is Chromium and WebKit browser layout.

Full independent Codex gpt-6-astra xhigh review: SHIP at d065c37.

Current head ca6e9513c8599f8fbbe98664563468700e0294e9 changes only the short-player padding from literal 40px to calc(var(--ds-space-6) + var(--ds-space-2)). The shared desktop tokens are 32px and 8px, so computed geometry stays exactly 40px. The matching design-token gate, scoped format/lint, and prepush gate pass at this head. Browser tests and captures above remain accurately bound to d065c37; no duplicate browser run was needed for the equivalent spacing expression. Independent Astra xhigh delta review and primary inspection confirm the same computed layout.

Review (independent Codex gpt-6-astra, xhigh): SHIP at ca6e951.

Changelog

Fixed: Inline videos’ Open in tab and Expand actions can be clicked independently and stay clear of the player’s own controls.

Lawrence, relayed by Leo (2026-10-22): "trying to click between the two of them". A browser-lane test measures the inline video's controls in real layout (Chromium and WebKit): every hit area at least 28 x 28 px, 8 px apart, a click on each lands on it, a click just off one lands on nothing that acts, and while it plays our buttons stay clear of the player's own rows. It fails on the base: Open in tab and Expand are 24 px, 4 px apart, a near miss plays the video, and while it plays they sit in WebKit's top corner row. The gallery gets the hovered and playing states for the before/after. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Lawrence, relayed by Leo (2026-10-22): "trying to click between the two of them". Each button is now a 28 px square click with its 24 px glass drawn inside, 8 px from the other, and their row keeps a 4 px margin that takes a near miss and does nothing (before, a click just off either played the video with sound). While the video plays they sit below the player's top row of controls (WebKit's Full Screen, Picture in Picture and Mute corner bars) instead of over it. What each button does is unchanged.

cmux-next guards / nightly-guards / workflow-guard-tests / release-notary is red on 14 of 19 fresh feat-cmux-next PR heads in the last 2:00:00, so it is most likely a base red, not this PR's. The base-reds lane has it; a base merge picks up the fix once it lands.

Review (codex gpt-6-astra xhigh, next-review): BLOCK at 11eaf48

[P2] chips.css:311: The fixed playback offset overlaps native controls on short videos. Videos have no minimum height. A 1920×400 recording renders at 480×100; the new buttons occupy y=45–73, overlapping WebKit’s bottom control bar at y=63–94 and intercepting its clicks. Previously, these buttons occupied y=6–30. Use a height-aware placement or move actions outside short players, and cover a short video in the browser tests.
