So you're saying that while there is an old Window object that the XMLHttpRequest interface object is on, it no longer has an associated Document object? I thought there was a 1:1 mapping. That would mean http://xhr.spec.whatwg.org/#dom-xmlhttprequest is bogus. If a Window object potentially has a Document object given this edge case I suppose what I would propose is that when it does not have one, XHR's document is set to null, and we throw for xhr.open(). -- http://annevankesteren.nl/
