Issue Summary

The @mentioned user in a resulting notification of an existing comment being edited is rendered as lower_user_name and user_key instead of the display name as expected. Conversely when adding a new comment containing an @mention the resulting notification displays the user's display name as expected.

This is reproducible on Data Center: yes

Steps to Reproduce

1. Create a new ticket
2. Add a comment with just text. For example "new comment added"
3. Save comment.
4. Wait 2 minutes
5. Edit the comment and add a users name using the html tag. For example "@username"
6. Save comment.
7. Look for the email sent to user.
8. The emails related to this one comment will only display the username/userkey.Expected Results

Expected Results

The notification triggered would include the @mentioned user's display name like we see when a new comment is added.

Actual Results

The @mentioned user's lower_user_name/user_key is displayed.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
