In the narrow comment margin, a new inline comment's composer lives in a popover next to its minimized badge. When you click outside the composer, the popover closes right away. The draft thread and its highlight only went away later, when the editor's selection change cleared the active thread. That left one painted frame showing the yellow highlight and a "1" comment badge. Now the popover's close handler clears the active thread for a draft, so the draft is removed in the same tick the popover closes.


Note

Low Risk
Narrow UX fix in comment popover close handling with targeted tests; no auth, data, or API changes.

Overview
Fixes a one-frame flash when dismissing a new inline comment composer in the minimized margin popover by clicking outside.

The popover onOpenChange handler now calls setActiveThread(null) when the popover closes, the comment is still a draft (isNew), and that thread is already active—so the draft highlight and badge disappear in the same tick as the popover, instead of waiting for the editor selection to clear. If the same outside press only activated the thread (isActive false), active thread is left unchanged.

Tests cover both cases: outside dismiss clears the active draft thread, and does not clear when the thread was not active.

📝 Summary

Summary by CodeRabbit

  • Bug Fixes

    • Dismissing a minimized new comment by clicking outside now clears its active thread and discards the draft.
  • Tests

    • Added coverage for clearing a new comment thread when it is dismissed outside.

Walkthrough

When a minimized thread closes, its open-state callback updates expanded. If the thread is new, the callback also clears the active thread. A test checks that an outside pointer press dismisses a new minimized thread and calls setActiveThread(null).

Switching comments in this layout can unexpectedly clear the selected thread and unsaved draft marks. Make dismissal clear only its own thread; the risk is narrow but worth fixing before merge.

the active thread only if it still belongs to the closing draft. Add a
