[jQuery] element.attr() bug in jquery 1.2.6?

Hi all,
I've run into a strange issue that I believe is a bug in jQuery 1.2.6.
I've posted a ticket along with a test HTML file at:
http://dev.jquery.com/ticket/2959
As far as I can tell, attr() is not properly updating the value of a
form attribute, although prior versions had worked fine.
Any help in resolving this, or providing a workaround would be greatly
appreciated.
Thanks in advance,
