On Android tablets, pressing Shift+A produces "AA" because the input event listener re-sends characters that xterm already processed via its keydown handler. Track keydown timestamps and skip input events that fire within 50ms of a handled keydown. Only affects touch devices (listener gated by isTouchDevice()).

Summary
On Android tablets, pressing Shift+A produces "AA" because the input event listener re-sends characters that xterm.js already processed via its keydown handler.
Fix
Track
lastKeydownHandledtimestamps on the xterm textarea. Theinputevent handler skips if a keydown was processed within 50ms, preventing the double-send while still catching Android virtual keyboard symbols (keyCode 229) that xterm misses.Only affects touch devices (listener gated by
isTouchDevice()).Test plan
