// in a document by the time this timer fires, the frame hierarchy teardown
// will continue. This can also be seen as implementation of:
// "Removing an iframe from a Document does not cause its browsing context
// to be discarded. Indeed, an iframe's browsing context can survive its
// original parent Document if its iframe is moved to another Document."
