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.
