Incorrect layout when specifying both corners with fixed positioning

Hello,
my name is Thomas Grundmann and I guess I have found a bug with fixed
positioning. Assuming the following file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>Test fixed possioning</title>
</head>
<body>
<div>hello</div>
<div style="
position:fixed;
top:0;
bottom:0;
left:0;
right:0;
background-color:red;">world</div>
</body>
</html>
Using this file the result should be a red colored div having 'world' as
content that covers the whole content pane (picture1, right side; made with
firefox) but the result is different (picture1, left side; made with FS
browser demo). It seems that if the left property has a different value
than 'auto' the right properties is ignored (handled as set to 'auto'). So
this behavior equals to the one for relative positioning. As far as I
understood the css2.1 specification this is wrong.
It is interesting, that this does not appear with absolute positioning.
For the FS screenshot I used the browser demo with the xhtml file as input
(modified the form.xhtml file).
regards
Thomas Grundmann
