Er, sorry, my testcase was supposed to be:, "foo");

running in window1.

In this case the "this" object is from window3, the function is from 
window2, and the caller of the function is in window1.

I fully expect the actual elements here to be created from window3 (this 
is one of the cases I expect are needed for web compat), but I just want 
to understand which of window1 and window2 is the "caller's Realm" in 
the IE case.
