Reviewed by Ben Nham.

If a page changes its title while in the background, allow the page to run in the
background, as long as the app is foreground. Previously, the page changing its
title would buy its an extra 8 minutes of background running time. We are now
more permissive and allow the page to run indefinitely in the background when we
detect this (as long as the application is foreground).
