Issue: When using the shortcut Command + Delete to clear a line of text, the next character I type in Thai unexpectedly appears as an English character, even though the input source is still set to Thai. After that, subsequent characters return to Thai as expected. Details: Affected apps: Notes, Messages, and some other native apps Not affected: Browser text fields (Safari, Chrome, etc.) Does not occur when using Option + Delete or just Delete macOS [insert beta version + build number] Mac model: [insert model] Input sources: Thai – Kedmanee, English – U.S. Steps to reproduce: Open Notes (or Messages). Switch to Thai input. Type a few Thai words. Press Command + Delete. Type again — the first character shows up in English. Expected: First character should remain in Thai, consistent with the active input source. Actual: First character shows as English, then input switches back to Thai.
