Problem

Closing a mouse-opened image preview could reopen its path tooltip and leave it visible while scrolling the timeline. Fixes #30508.

Change

Preserve the opener's focus visibility when closing the preview, so Escape does not turn mouse focus into keyboard focus. Timeline scroll dismissal now retains tooltips only for keyboard-visible focus, allowing a hovered, mouse-focused image tooltip to close without blurring the image.

Keyboard tooltips still stay open during scrolling, preserving #15455. The shared components cover web and desktop; mobile has no DOM tooltip path.

Scope and approval

This qualifies as a small, focused fix for an obvious bug: a reproducible tooltip dismissal failure in the existing image-preview flow. It preserves existing keyboard behavior and introduces no new workflow or product default.

Verification

• The preview regression failed before the fix: the tooltip survived scrolling, and Escape restored a mouse opener as :focus-visible. It passes after the fix.
• Added keyboard-focus and hover-then-keyboard-focus scroll cases at the tooltip layer. Both fail against the initial unconditional-dismissal patch and pass with the final fix.
• vp test run apps/web/src/components/chat/ExpandedImageDialog.browser.test.tsx apps/web/src/components/ui/tooltip.browser.test.tsx: 7 passed.
• vp run check:changed upstream/main: passed format, lint, both knip checks, affected typechecks, browser tests, and React Compiler verification.
• Used test-t3-app against isolated development state with a synthetic image conversation in the real Electron/Chromium client. Verified preview open/close, hover, scrolling with image focus retained, and command-palette opening without a lingering tooltip. Native macOS and non-Chromium browsers were not tested.
• Rebased onto current upstream main; its intervening change only touched file-metadata expiry in client-runtime.

Approvability

Verdict: Approved at 2ee291b

Macroscope's review found this PR approvable — The fix lets mouse-focused image tooltips dismiss on scroll after closing a preview while preserving keyboard-focused tooltips. Its effects are limited to transient focus and tooltip presentation.

Walkthrough

The image preview restores focus to its opener with the recorded focus-visible state. Tooltip scroll dismissal now checks whether the active element inside its trigger matches :focus-visible.

Explanation

The production changes are limited to image-preview focus restoration and tooltip scroll dismissal. The browser tests directly verify those behaviors. These changes support [#30508] and show no demonstrated unrelated scope.

Full details: Linked Issues check

Explanation

Issue [#30508] requires the image-path tooltip to close after preview use and on timeline scroll. ExpandedImageDialog.tsx preserves the opener's :focus-visible state, and tooltip.tsx now dismisses hovered tooltips for mouse-focused triggers while retaining keyboard-focused tooltips. The added tests cover these behaviors. The issue also requires that the tooltip never appear over the command palette or an image dialog. The reviewed changes do not change tooltip dismissal when either overlay opens, tooltip layering, or tests for either overlay case. The current evidence does not establish that requirement as implemented.

Resolution

Implement the [#30508] overlay requirement. Dismiss or otherwise prevent the image-path tooltip when the command palette or image dialog opens, and add automated coverage for both overlay cases.

Keep the production image as the focus target and test keyboard activation.

The production trigger is the <img> with role="button" and a custom Enter/Space handler. A native <button> would test a different focus target and native activation behavior. Keep the image fixture, add the production trigger semantics, and exercise the keyboard-visible restoration path in the existing test.

Evidence

Click the file-backed image, close with Escape, move away and hover again, then scroll without clicking. Repeat with Tab/Enter keyboard focus. Also check Ctrl+K.

Environment: real web app, Chromium 156/Linux, 1280×800, light theme; identical synthetic replay seed and driver on fresh isolated databases. Workspace paths redacted; stills crop the sidebar.

Scenario and synthetic seed · Runtime observations

Observed: base restores keyboard-visible focus after mouse preview and retains the hovered tooltip on scroll. Head restores mouse focus without a keyboard ring and dismisses its tooltip on scroll; image focus remains. Keyboard-visible focus and its scroll behavior remain intact. Ctrl+K dismissed the tooltip on both commits.

AI-assisted; verified with the tests and tools listed above.

Not shown:

• Reported tooltip overlap over the command palette or preview dialog was not reproduced: Ctrl+K dismissed the tooltip, and preview dialogs appeared unobstructed on both commits.
• Desktop Electron shell was not exercised; verification covered the real web client.
