[jQuery] Firefox/Mac scrollbar bug on slide effects


http://lab.atomeye.com/
This only applies to Firefox on Macs.
In the above example the first 'close' targets an element with
'overflow: auto;' and opens/closes it correctly.
In the second example the element with 'overflow:auto' is nested and
the scrollbar remains visible when the parent div closes.
Is there an easy fix for this?
