Now consider a web page with two subframes and a script that has

w1.XMLHttpRequest = w2.XMLHttpRequest;

What's the document associated with xhr? Is it w1.document,
w2.document, or window.document? The concept "the Window object for
which the XMLHttpRequest interface object was created" doesn't seem to
be defined anywhere....
So this was defined this way the last time you brought this up. I believe
it should be w2.document which is different from how most constructors
behave (e.g. Image), because that is what IE does and you wanted to be
compatible with that. The testsuite does not test w1.XMLHttpRequest =
w2.XMLHttpRequest explicitly, because nothing should happen there except
referencing the interface object from elsewhere. It does test constructing
an interface object from a different window and then checking how URLs
resolve. See the multi-window tests.
