I have noticed a bug with using a form element named action, which
funnily enough only effects IE. If you need to do anything to or based
on that action element in IE with Javascript, it has a lot of problems
differentiating the form element from the form action attribute, and
gets them a bit confused. It's similar to the IE name/id bug.
