Here is a reduced test case. The citibank site in question breaks if 
the width accessed during loading is 0 instead of the correct value. 
This requires a layout since it is a percentage width.

A fancier solution would be to block execution of scripts if they will 
require a layout until all stylesheets are in, but it's in general 
impossible to tell this up front, and it's hard to pause script 
execution in the middle.

Note that this will not affect the vast majority of sites at all (w/ my 
fixes).

<html>
<head><link rel='stylesheet' 
href='https://www.accountonline.com/svc/content/Style.css' 
type='text/css'></head>
<body>
<table width="160">
	<tr><td>
		<nobr>Compare Payment Options</nobr>
	</td></tr>
	<tr><td>
		<table width="100%">
			<tr><td><img src="" name="widthtest" width="100%"></td></tr>
		</table>
	</td></tr>
</table>
<script>
	alert('document.images["widthtest"].width = ' + 
document.images["widthtest"].width + ', should be non-zero');
</script>
</body>
</html>
