@ Mention used to allow selection w/ Enter key - now needs mouse click

When using the "@mention" if you hit Enter, the highlighted suggestion would auto-complete. Now we are on JIRA 6.2.1 and you have to mouse-click the highlighted row for the @mention to commit. IE10, Firefox and Chrome all display this behaviour.

Answer

This issue is caused by Zephyr plugin. Temporarily disabling the plugin will get the Mention feature to work properly again with pressing Enter.

Currently this issue is being tracked by Zephyr in their internal project. For more information, you can contact Zephyr support and mention the issue key ZFJ-1331 to them.

Workaround

Thanks to everyone's feedback, a Mouse Click or pressing Tab is able to select the mentioned user instead of pressing Enter.
