User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de-AT; rv:1.0.0) Gecko/20020623 Debian/1.0.0-0.woody.1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; de-AT; rv:1.0.0) Gecko/20020623 Debian/1.0.0-0.woody.1

Example:

<div style="position:absolute; top:0px; left:0px; border:#ff0000 2px solid;">
<div style="position:absolute; top:0px; left:0px; height:200px">
text
</div>
</div>

The height of the outer div should be 200px according to the definition at:
http://www.w3.org/TR/REC-CSS2/visudet.html#abs-non-replaced-height

But mozilla sets the height to 0px.

that's a table bug.  This is not.

This _is_ invalid however.  The inner div is out-of-flow and should not affect
the parent height....  This falls under item 4 at
http://www.w3.org/TR/REC-CSS2/visudet.html#abs-non-replaced-height:

  4. If at this point both 'margin-top' and 'margin-bottom' are still 'auto',
     solve the equation under the extra constraint that the two margins must get
     equal values.

The margin values are equal and negative in this case.
