[Laurent Martelli]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20050105 Galeon/1.3.19 (Debian package 1.3.19-1ubuntu1)

The CSS2.1 specs says: "In the absolute positioning model, a box is explicitly
offset with respect to its containing block.". But it looks like the offset is
relative to the page, and not the containing box.

Reproducible: Always

Steps to Reproduce:
See the attached test case.
Actual Results:  
The absolute red box is in the top left corner of the page. 

Expected Results:  
The absolute red box should be in the top left corner of the box with text in it.

Indeed, I missed that definition, I had only looked at
http://www.w3.org/TR/2004/CR-CSS21-20040225/visuren.html#containing-block

Sorry for the burden.
