In apps/desktop/src/preview/PickPreload.ts, the annotation session's onKeyDown called teardown(true) on every Escape before checking for an IME composition. An Escape meant to dismiss an IME candidate in the comment therefore removed the overlay, the selection and the draft. The Escape branch now requires !event.isComposing, the same check the Enter-submit and dictation handlers next to it already use. A composing Escape now falls through to the existing guard that ignores keys typed in input/textarea elements, so the IME handles it and the annotation stays. Plain Escape still cancels annotation mode. Nothing changes on screen beyond the bug going away, and no regex or parser was added. Verified at unit level only; the real desktop reproduction was not re-run after the fix.

Fixes #35629

Reproduction on main

Commit b63d3c5 (origin/main). Ran vp run dev:desktop under headless-desktop with T3CODE_DEV_SEED=0, a fresh database and Electron remote debugging enabled. Finished onboarding, added a local git folder as a project, opened the Browser surface on a local static page (python http.server) and clicked the annotate button in the preview chrome. Clicked a paragraph in the guest page with real CDP mouse input, which opened the comment editor. Typed 'draft ' with Input.insertText, then started a real IME composition with Input.imeSetComposition('にほん'); the screenshot shows the highlighted, unfinished composition. Sent an Escape keydown with Input.dispatchKeyEvent. Result: the overlay, the element selection, the comment editor and the draft all disappeared, and annotation mode turned off. A probe input in the same page confirmed Chromium delivers that Escape keydown with isComposing=true and keyCode=27. Captures: before https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/db3ad2174772ce18/before-escape.png, after https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/3c1e59454a635f1f/after-escape.png. Unit level: a new case in apps/desktop/src/preview/PickPreload.test.ts dispatches a composing Escape on the comment textarea and fails on main (host detached; 3 existing tests pass).

Evidence

Real Linux Electron app on both commits, fresh databases with seeding disabled, identical synthetic page, light theme and 1100×780 viewport. Enable annotation, click the paragraph, type draft , start unfinished にほん using Chromium's IME composition input, then press Escape. Base tears down the annotation and loses the draft; head preserves the selection, editor and draft にほん. After committing composition, ordinary Escape still cancels on head.

Ordinary Escape control on head:

Identical recording driver, synthetic page, IME probe driver. The probe confirmed trusted Escape with isComposing=true and keyCode=27 on base and head.

Not shown:

• OS-native IME candidate-popup dismissal with a physical keyboard was not exercised; this proof uses real Chromium CDP composition input matching the triage reproduction.

Tests

On factory/repro-35629 before the fix: vp test run src/preview/PickPreload.test.ts (apps/desktop) had 1 failing (the composing-Escape case: host detached) and 3 passing. After the fix: vp test run src/preview/PickPreload.test.ts src/preview/AnnotationKeyboard.test.ts passed 5/5. vp run check:changed passed format, lint, knip, typecheck (2 packages) and tests.

Approvability

Verdict: Approved at 825272f

Macroscope's review found this PR approvable — Escape during IME composition now leaves the preview annotation open, while normal Escape cancellation is unchanged. The change is limited to annotation keyboard handling and presents no obvious material risk.

Walkthrough

The desktop preview annotation handler now ignores Escape keydowns during IME composition. A test checks that the annotation remains connected and the comment draft is preserved.

Merge Risk: Low · up to 82527

This fixes the main case where Escape in an IME dismissed the whole annotation. A narrower IME ordering could still discard an unsent draft, and a one-line guard on the 229 keyCode would close it. This is worth a small follow-up and need not block the merge.

Full details: Title check

Explanation

The title names the fix precisely: Escape during IME composition no longer cancels a preview annotation. This matches the main change in PickPreload.ts (the Escape branch now requires !event.isComposing) and the added composing-Escape test. The title follows the conventional commit form the template asks for, and it is specific enough for a teammate scanning history.

Full details: Linked Issues check

Explanation

[#35629] The issue requires that Escape during IME composition in the preview annotation editor not cancel annotation mode, and that ordinary Escape still cancels it. The whole-PR diff (merge base b63d3c5 to head 825272f) changes one line in apps/desktop/src/preview/PickPreload.ts: the Escape branch of onKeyDown becomes event.key === "Escape" && !event.isComposing. A composing Escape no longer calls teardown(true). Non-composing Escape still runs the same branch, so ordinary cancel behavior is unchanged. The PR summary reports a new unit test in PickPreload.test.ts that dispatches a composing Escape on the comment textarea, and reports that it fails on main and passes after the fix. I did not read that test file. The fall-through path for composing Escape (the input/textarea guard) was described by the author but not re-read in this review, because the file read was truncated. The real desktop IME reproduction was not re-run after the fix, and the Evidence section is still pending. Native OS IME delivery is unverified, as the issue states.

Full details: Out of Scope Changes check

Explanation

The code change is a single condition added to the Escape branch of the annotation keydown handler in PickPreload.ts. The test case described in the PR summary covers the same behavior. The PR summary also lists no other production changes. The change maps directly to issue #35629 and does not touch unrelated behavior. No out-of-scope change was identified.

Full details: Description check

Explanation

The description states the problem, the change, the linked issue (#35629), reproduction steps, and detailed verification with before/after evidence and test results. It follows the template's Problem, Change, Scope, and Verification sections. It does not use a conventional commit title in the body, and the Scope section does not explicitly say why the fix is a bug fix rather than a feature. These are minor gaps, so the description is mostly complete.

Ignore IME-processed Escape keydowns that report isComposing as false.

An IME can deliver the Escape that closes composition after compositionend. In that case isComposing is false, so the guard passes and annotation mode is cancelled. The keydown still carries keyCode 229. Add that check to the guard. keyCode is deprecated, but browsers still use it for this case.
