Right.  We already do this, sans popping a state object.

No.  The state object is attached to the session history entry, not to
the page's URI.  If you close a tab, all its session history entries
go away.  If you navigate to a page which was open in the tab you just
closed, that new instance of the page won't be aware of the old page's
state object(s).

A navigation on a new tab would get an entirely new environment.
Otherwise, like you suggested, this would be very confusing.
