Handling new frames and frame navigations with find-in-page during a find
session.
This patch implements new find-in-page functionality that allows for frames
that are either newly added or navigated during a find session to be
automatically searched so that matches in their new content are
automatically highlighted and included in the results shown in the find bar.
Also, there is a fix included in this patch to prevent the find-in-page bar
from closing when a subframe navigates (the find session should only end if
the main frame navigates).
