How should this behave in a situation like Firefox's "undo close tab", 
where the resulting tab has a brand-new window object but the 
window.history has been deserialized from a string representation.  So 
it's a new object, but has the same information in it as the old one 
used to.

Presumably in such a case this should be treated as "the same" browsing 
context in spite of the Window object being totally different?
