User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv:1.9.2.15) Gecko/20110303 Firefox/3.6.15 ( .NET CLR 3.5.30729)

An xhtml DIV inside a foreignobject of a SVG document does not render the content with a CSS property 'position:fixed'.
FF does not return ant error and the DOM inspector shows the right block position but content still empty !
Works fine with Webkit (chromium 10.0.629.0 (70502)
The bug exists also on Linux FF4.0 beta13

Reproducible: Always

Steps to Reproduce:
Run this SVG code:
<svg xmlns="http://www.w3.org/2000/svg">
<style type="text/css">div { position:fixed; background: #aaa; } </style>
<foreignObject width="100px" height="100px">
<div xmlns="http://www.w3.org/1999/xhtml">TEXT</div>
</foreignObject>
</svg>
Actual Results:  
empty page

Expected Results:  
'TEXT' string rendered

I have given a minimal example to reproduce the bug but my initial request was to embbed a full HTML5 Ace editor inside an SVG code. (Ace request a fixed div)

roc, the frame is there but we seem to not end up painting the div... any idea why?

Treat foreignObject as a fixed position containing block.
