I see you have done some work to prevent reflow loops with percentage 
root heights > 100%, but how does your patch handle an iframe document 
that looks like this? (I can think of nastier testcases also, where 
"bottom"  is embedded further down in the document)

<html>
<head>
</head>
<body>
<div style="position:absolute;bottom:-5px;">This will force a scrollbar 
on the document</div>
</body>
</html>
