209943 - Visiting this page locks up Mozilla even though the XHTML and CSS both validate

Status: RESOLVED DUPLICATE of bug 176305

(Core :: Layout, defect)

Description

[mozilla]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.0.3705)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030612

Visiting this page: http://www.visualpointdev.com/marylandsbest/bug.asp in 
Mozilla seems to lock up Mozilla.  The page never loads, the UI stops 
responding and it requires me to end the application in Task Manager.  Both the 
HTML and the CSS on the page seem to validate according to the W3C validator.  
It seems to have something to do with the form on the page because 
http://www.visualpointdev.com/marylandsbest/  displays fine and it uses the 
same stylesheet and header/footer.

Reproducible: Always

Steps to Reproduce:
1.Go to http://www.visualpointdev.com/marylandsbest/bug.asp
Actual Results:  
Mozilla stopped responding.

Expected Results:  
Mozilla should display the page.

odd

Mozilla OS X 2003061903 - the borwser doesn't lock up, but the window does sort
of stalls, acts a bit unresponsive/sluggish, never stops displaying the old page
(allthough scrollsbars seem to function they don't scroll the page).

I can still close the window, open new windows and things like the javascript
console, etc. so its not a full hang.

Nothing really stands out at me looking at the code... except that there's an
awful lot of % based dimensions including on the body (but not html)... and
things taken out the the document flow with position:absolute... perhaps theres
something in one of the combinations that moz is having problems resolving.

testcase needed

The page sets overflow:scroll on an <option> element.
