Overwriting a text with a letter that needs multiple keys using IME (input method editor) on MacOS doesn't work
Steps to reproduce
1) Create a text of some kind (doesn't matter whether English or CJK text)
2) Enter edit mode
3) Drag-select a text
4) Try to input a CJK text in IME
What normally happens in other software or when inputting an English text in MuseScore:
The drag-selected text gets deleted and replaced with new text.
The drag-selected text doesn't get deleted and new CJK text appears in back (When using Japanese) or front (When using Chinese) of the drag-selected text.
A simple workaround is to delete the text using backspace and just input the CJK text in IME.
