I saw this thread and updated it to 4.9996, but the operation did not change.
When I assigned Caps Lock to Command(L) using BTT's remap function according to your suggestion, it became a practical operation.
Now you can resume your comfortable work.
Thank you.
However, this is only a workaround, and the movement is different from the original action.
There may be other Asian language users who are in trouble using IME.
I hope the bug will be fixed.
