Given an HTML doc with an absolutely positioned div that has CSS
'visibility:hidden' and is off the screen when the page is initially loaded, if
the div's visibility property is set to 'visible', it diplays the content
correctly, but the border and background attributes apply as if the div width
was zero.

Reproducible: Always

Steps to Reproduce:
1. Load a web page with an offscreen, invisible div. (see test case attached)
2. Trigger Javascript to make div visible. In the test case, scroll all of the
way to the right and mouseover the link.

Actual Results:  
The div content displays normally, but the border and background styles display
as if the content width equalled zero.

Expected Results:  
Displayed the border and background styles across the full width of the div.

Attachment: this file contains four hidden divs. The rightmost one (scroll all of the way over) will not display border and background properly.

This test case shows the buggy behavior. Load, scroll all of the way to the
right, mouse over the rightmost link.

Please test with trunk builds before filing layout issues
ftp://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/

Firefox 1.0.x is using gecko 1.7 (from april 2004) that is outdated when it
comes to layout issues.

Please reopen if y ou can reproduce using a nightly trunk build.
