I'm using JIRA cloud edition.
When input japanese, convert 'kanji' and 'hiragana' characters from alphabet input.
In many environments, use the return key to confirm the characters.
But, when input a comment to the task of JIRA, pressing return key to confirm the characters, ADDS UNNECESSARY NEW LINES. It's problem.
Environment:
macOS 10.13.5
Safari 11.1.1 (13605.2.8)
ATOK (Japanese IME) 31.0.0
