Compared to Firefox some elements are in wrong positions, some elements are completely missing. If you go to a subpage like http://www.itwire.com.au/content/view/10555/532/ text size is wrong and some text is missing. Ad banner area displays pieces of visible HTML code. Parsing problem perhaps?

I cannot reproduce this bug in r22044. Could you attach the source or a web archive?
No repro in r24513
Nothing to work with here anymore.
