Greenhopper 6.1.1 has problems with zooming on both FF 18 and up-to-date Chrome

Got a report from an end customer:

In the new scrum board, plan mode, if the page is zoom in, a part of the edit issues window cannot be accessed and the story points cannot be defined (see the attached picture).

We upgraded to Greenhopper 6.1.1 a couple of weeks ago from Greenhopper 5 based release.

Able to reproduce the issue with Firefox 18.0.1 and also Chrome on any rapid board and then zooming. Saw that there is a related issue GHS-5666, but that has supposedly been fixed.

One should be able to reproduce with any instance.

I see a related new report from Mozilla.org at http://support.mozilla.org/en-US/questions/947443, but the problem also happens in Chrome.
