427971 - Content of long div not all displayed when "overflow: scroll" or auto

Status: RESOLVED DUPLICATE of bug 215055

(Firefox :: General, defect)

When viewing a simple page (such as that generated by the attached php), the div's contents are truncated.

The first 1637 lines (on my system) render fine, then there is enough blank space to contain the rest of the text, but no text in there. The div's scroll bars run all the way to the bottom of the page (grayed out), but there is no content displayed. FF continues to run ok, and doesn't show any signs of stress about the large page, it just only shows the first 1600 or so lines of content. The final displayed line has only the top part displayed down to some apparent pixel limit from the top of the page / div.

This only happens when the div has an overflow of "scroll" or "auto". "visible" and "hidden" result in the entire contents being displayed correctly.

Loading the same page in IE, safari, and opera all show the full page with all content.

Reproducible: Always

Steps to Reproduce:
1. Copy the code above onto a handy php server, or create a page with over 1700 lines of content
2. View the page in Firefox
3. Scroll down and see the text stop being rendered.
Actual Results:  
All text rendered fine down to 1637. line 1638 has only the top few pixels of the text shown

Expected Results:  
All text rendered all the way down to line 10000.

Hi,
I did see bug 215055 when checking I was not submitting a duplicate, but didn't check, the test cases. The test case at "a testcase from a bug dupped to this one" ( https://bugzilla.mozilla.org/attachment.cgi?id=249560 ) there does seem to demonstrate the same thing as I'm experiencing. Sorry for the duplication, and good luck fixing it chaps :-)
