User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b5) Gecko/2008050509 Firefox/3.0b5
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b5) Gecko/2008050509 Firefox/3.0b5

Printing fails to respect CSS 2.1 position:absolute coordinates defined for paged media. Element is positioned instead at the top of page, printed on top of everything else.

The page is valid XHTML 1.0 Strict with CSS 2.1

Printing works as expected on Firefox 2.

Reproducible: Always

Steps to Reproduce:
1. Print
Actual Results:  
Positioned element is positioned incorrectly / ignoring positioning coordinates

Expected Results:  
Element positioned according to CSS

Some forums recommended disabling Xulrunner. This appears to have no effect on the result.

More detail: The bug appears to concern only positions affected by page height. See another example:

http://www.kulma.net/simo/example/example2.html

Positioning by percentage of height fails (top:50% and bottom:50%) as fails also positioning by distance from bottom of the page (bottom:50pt).

All this does work with Firefox 2

Since Ubuntu now has version 3.0, just to add that this bug still exists in Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9) Gecko/2008061015 Firefox/3.0

Anybody got an idea how difficult a bug this is?
Since it worked (works) perfectly on FF2 I wonder if I would be able to fix it myself, now that I'm back at the univerity and a bit more into programming... How much the CSS stuff changed from FF2 to FF3?

This seems to work on FireFox 3.5, so I guess it is no longer important...
