Brent, do the tests need to be updated?

No, but I think this assertion isn't quite right. I'll fix this to get the bots green.

In Bug 178183 I made a mistake in the topDocument to use for logging user interaction. I was using 'topDocument->topDocument()', which I should have been using 'm_frame.document()->topDocument()'.

I'll obviously fix my lack of an "address-of" operator before landing. :-\
