dcheng@, does OOPIF affect this issue?

OOPIF doesn't affect this issue either way: currently the Location object is bound to the Window object. So if the Window object changes, we will get a new Location wrapper. When we swap local to remote or remote to local, we get a new Window and thus a new Location object.

I'm not sure why the "navigation from initial about:blank page" case is failing, since I would have expected that to work.

This issue has been Available for over a year. If it's no longer important or seems unlikely to be fixed, please consider closing it out. If it is important, please re-triage the issue.

Sorry for the inconvenience if the bug really should have been left as Available.
