Issue Summary

Writing the Word "Jira" in the Comment of an issue prevents the user from hitting space to enter whitespace. This only happens in Safari.

Steps to Reproduce

1. Open an issue
2. Hit the "Add a comment" button
3. Start typing the comment, until type Jira

Expected Results

After typing Jira, hit the space and keep typing

Actual Results

After typing Jira, when the space key gets hit, nothing happens.

Workaround

1. Type "Jir" and then keep writing, when it's finished add the "a" from Jira
2. Type all the messages but the word "Jira", when it's finished, write "Jira" in the correct part.
