Greetings.

I'm using Aegisub 3.4.2 Release on an arm64 MacOS 14.6.1 (23G93).

After upgrading from 3.2.2 to 3.4.2, I'm encountering issues with MacOS's built-in Chinese(partial) and Japanese(unusable) IMEs.

For Chinese IME(pinyin):
Input preview is not available. Candidate selection box would not stay along input. Pressing "Enter" will create new lines instead of allowing raw keyboard input to be recorded.
Screenshot is shown for Aegisub 3.4.2(bugged) and 3.2.2(expected) after typing "zhongwenshurufa"(Chinese IME)

For Japanese IME(romaji):
Input preview is not available. Candidate selection box is not appearing for most of the time(unless IME is predicting). Commiting candidate selection through double-click(ignored) or "enter"(creating new lines) is impossible, rendering Japanese IME completely unusable.
Screenshot is shown for Aegisub 3.4.2(bugged) and 3.2.2(expected) after typing "nihonngo"(Japanese)

Hope this could be addressed soon.

Best regards.
