didShowTransition ?  Is the WebLocalFrame being notified of something or being
instructed to notify someone else?  If so, who?

Why is elementsToHide represented as an int?

+    virtual void setupTransitionView(const WebData& markup) = 0;

What does it meant to setup a transition view?  Is this a request to navigate
the WebLocalFrame?  Maybe we should switch the frame into transition mode and
then kick off the navigation?  This API doesn't make much sense.

Done.
