564836 - An iframe taller than 32,767 pixels high does not display correctly.

Status: RESOLVED DUPLICATE of bug 333994

(Firefox :: General, defect)

Description

[iframe.limit]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.9) Gecko/20100315 Firefox/3.5.9 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.9) Gecko/20100315 Firefox/3.5.9 (.NET CLR 3.5.30729)

When an iframe height exceeds roughly 32,767 pixels, the size of a signed short (16-bit) integer, Firefox no longer displays/renders the iframe correctly.  Using firebug, the element itself is the correct height, but it cuts off the content early and introduces a scrollbar leaving the remaining pixels below the cutoff limit completely blank.

Reproducible: Always

Steps to Reproduce:
1. Create a page with an iframe set to a height larger than 32,767 pixels.
2. Fill the iframe with enough content to fill the height past 32,767 pixels.

Actual Results:  
Content cuts off early with a scrollbar but the iframe area is the correct height.

Expected Results:  
Display the iframe without problems.

This problem is fairly minor.  I'm probably the only person to ever encounter this bug.  I had to have approximately 40 printed pages of content on a single webpage in an iframe to even encounter it.

Still, it would be nice if this was an easy fix and could be in the next release.

This is a dupe of bug 333994. It's fixed in Firefox 3.6. Due to the nature of the fix, it will not be fixed in Firefox 3.5.x.
