**Steps to reproduce:** - In Firefox on Linux, edit <h1>ab<u>cd</u></h1> - Press end, left, left (so the cursor is just after <u>) - Type 'ㅎ' in Ibus Korean (i.e. press 'g') **Expected** The DM and DOM stay in sync **Observed** The character 'ㅎ' is underlined in the DM, but not in the DOM **Explanation** This is because the IME (like many others) doesn't emit keyDown events, so ve.ce.Surface#keyDownState.focusIsAfterAnnotationBoundary doesn't get used.
