Can't input Japanese character space.

[thanks2music]

Hi, there.
I have the same problem with Windows and Android Google Chrome.

Steps to Reproduce

Japanese space does not work properly.

1. Mac OS X System Preferences -> Keyboard -> Input Sources , add Japanese and check Show input menu in menu bar .
2. Click input menu icon in menu bar and select あ Hiragana
3. In the Trix Editor, type, say, “aaaa” (Japanese string ああああ should be displayed).
4. Type Japanese space in the trix-editor.
5. Japanese space will be replaced with 1 byte space. After input, the cursor position is also incorrect.
