Getting a handle to login-popup is not a big deal. You could get that 
anyway by just opening the login popup window yourself anyway. The fact 
that the site overwrites itself is a bigger concern (usability, though, 
not security); but I don't see what we can do about that.

Indeed, I tried doing that earlier and you complained, saying it would 
break sites. :-)
