See upcoming testcase.
It only happens in Standards compliance mode.

Hovering over the span with the text "hover me and see table grow" causes the
textarea and the surrounding table to grow to the right.
This is the css of the span:
span:hover { margin-top: 1px;}

Probably a dup of the other MEW and form control bugs...

I can't see the bug anymore in today's build:
Mozilla/5.0 (Windows; U; Windows NT 5.1; @AB_CD@; rv:1.8a4) Gecko/20040924
Firefox/0.9.1+

I can see the bug in:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a3) Gecko/20040829
Firefox/0.9.1+
But I can't see it anymore in:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a3) Gecko/20040901
Firefox/0.9.1+

Maybe this bug has been fixed by fixing bug 246999 (but I have no idea).
