(Core Graveyard :: GFX: Mac, defect)

Description

[will]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/312.1 (KHTML, like Gecko) Safari/312
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

When changing the visibility of a layer from visible to hidden the scroll bars remain visible.  I have 
checked the PC version of Firefox (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/
20041107 Firefox/1.0) and this issue does not exist in it.

The example url leaves the horizontal scroll bars of each scrolling layer visible when the mouseover 
javascript makes the layers hidden.

Reproducible: Always

Steps to Reproduce:
1. Load the page.
2.
3.

Actual Results:  
The page was initially rendered wrong and continued to be wrong.

Expected Results:  
The expected results were to have the scroll bars become hidden when the layers became hidden, it is 
correct in the PC version I tested (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/
20041107 Firefox/1.0)

Seems to be a Mac only bug.
