There are some strange behaviors when entering Japanese with an editor.

Steps to Reproduce:

1. Turn on IME (standard macOS IME)
2. Enter the character string you want to convert
3. Just display IME conversion candidates and move with the cursor keys (up and down). I do not notice it by just entering with Enter key
