List item is duplicated unexpectedly when typing Japanese characters using IME

Summary

When typing Japanese characters using the IME (i.e. input method editor), a list item is duplicated unexpectedly after Enter key was pressed.

Steps to reproduce

See screencast's 2nd example.

1. Enable Japanese IME
2. type n, i, h, o, n, n, g, o keys
   • this results in にほんご
   • when using Japanese IME, inputing characters are not fixed at this point because they may be converted to KANJI
3. type ENTER key
   • * にほんご is duplicated in the next line

What is the current bug behavior?

The duplicated list item is added in the next line

* にほんご
* にほんご

What is the expected correct behavior?

No list item is added (just finished IME conversion mode)

* にほんご

Relevant logs and/or screenshots

1. 1st example * English is expected behavior
2. 2nd example * にほんご is bug behavior
3. 3rd example * 日本語 is expected behavior
   • when typing SPACE key before ENTER key to convert にほんご (KANA representation) to 日本語 (KANJI representation), the bug is not reproducible.
