if the code shown below is used on a web page that contains a lot of content such as a forum thread with a lot of replies. it will cause half of the page to fail to render 

g4 uses code similar to this but they don't have the !important command in theres so the browser doesn't use it unless it wants to

I reported this bug when firefox 2 was the latest but I was not able to find out what wa causing it until firefox 3 came out and the problem went away so when i looked into what changed, I noticed that firefox 3 wasn't reacting to the code below unless the !important was added and when I added that to get horizontal scrolling since it is needed for forums when large images are posted, I noticed the problem came back

#divBody { 
	overflow: auto !important;
}

to add this code to the page I used the stylish extension which allows you to inject your own css

I included a video showing this problems also

Reproducible: Always

Steps to Reproduce:
1.install stylish extension
2.create a script for the g4 forums using this code 
#divBody { 
	overflow: auto !important;
}
3. head to this link http://forums.g4tv.com/thread.jspa?threadID=18248&tstart=0
(make sure the thread is set to show 100 posts or more per page )
4. enable and disable the script to compare how the page loads, it causes half of the page to fail to render even if the scroll bar is not visible due to the page not requiring all of the horizontal space
Actual Results:  
much of the page failed to render 

Expected Results:  
the entire page should render regardless of this script being used or not. when opera browser uses it, it has none of these problems
