Feedback form in Chrome does not display correctly

It appears that with the latest JIRA release some changes were made to the Feedback form which causes it to hide the e-mail field in Chrome.

If I put a Chrome window side-by-side with Firefox I can see that the Feedback form is much taller in Firefox (approximately 542 pixels) compared to Chrome (approximately 452 pixels).

Side by side screenshot attached for reference.

All of my customers use Chrome, so this is a big problem for me. I'm sure a lot of others will be impacted as well. Please let me know how soon this can be fixed.
