[Intent Picker] Navigation misinterpreted as back/forward button press.

PageTransitionGetQualifier is misinterpreting a user selecting a link
as a back/forward or typing in URL bar, disabling intent picker from
displaying when it should. We need to mask out the client redirect such
that the intent picker shows.
