I was not sure how to report it, under the bug tracker or somehow but if you click inside a bug on the bug tracker you see duplicate headers, like frame within the page
Picture is worth a thousand words:
http://www.magentocommerce.com/bug-tracking/issue?issue=1618
Looked exactly like that, well done, I guess someone got to the post and got it fixed to make my URL look foolish, Ill post a screenshot next time i guess. But hopefully they will see your URL and get it fixed as well.
