384614 - Iframe height maximum, pixels past 32768 not rendered

Status: RESOLVED DUPLICATE of bug 333994

(Firefox :: General, defect)

Description

[Ben Zajac]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4

On Firefox 2.0.0.4 Win32:
http://nebcajaz.com/test_frame.html to view. Scroll to the bottom of the parent page containing the iframe.

It seems with an iframe in firefox on windows, anything past 32768 pixels down inside the iframe will not display. Possible rendering problem. The magic number that is the cut off drawing point seems to be 2^15 (max value of signed short, I believe).

Firefox 2.0.0.4 on ubuntu 7.10 (i386) on a core 2 duo doesn't have the problem, which leads me to believe it is windows only, but that is unconfirmed. More testing required.

Problem shows on both WinXP and WinVista.

Reproducible: Always

Steps to Reproduce:
1. Create an iframe with a large height : iframe height=33000 src=somewhere.html
2. Scroll down to bottom of page.
3. Look for bottom scroll bar button.
Actual Results:  
Bottom of iframe is not painted.

Expected Results:  
Whole iframe shows
