This is right.

I thought about this issue. But implementing it this way is beyond my  
knowledge about the implementation details. The interesting question  
is, how IE does it. Do they really change the child nodes? I don't know.

I fear the effort to fix it "the right way" isn't worth it. But this  
cannot answered without real examples.

Yes. But you need a patch which temporarily fixes an iFrame issue.  
Otherwise you cannot log into it. If you like, I would send you a  
demo account and the patch.
