User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b2) Gecko/20050531 Firefox/1.0+
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b2) Gecko/20050531 Firefox/1.0+

Visting the mentioned site in Deer Park Alpha 1 the inital focus of the site
requires 2-3 seconds of 100% CPU usage, post loading (e.g. tab was
backgrounded). Switching to another tab or application, and switching back the
focusing of the site requires another second of 100% CPU usage. 

Disabling CSS the site functions properly. CSS is valid (according to w3.org).
With CSS the site functions fine with FF 1.0.4 and Mozilla 1.7.8. 

Reproducible: Always

Steps to Reproduce:
1. Go to http://core.org.au/ with CSS enabled


Actual Results:  
Momentary max CPU usage.

Expected Results:  
Smooth browsing.

you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.
