Ah, we do clear it each time the Frame navigates.  That's good, but it should be
done by the ScriptController.  What if the user closes the dev tools (or
PageDebuggerAgent shuts down some other way)?

I'll need to check with Pavel Feldman, but I believe that closing the front-end
has no effect on the dispatch of didClearWindowObjectInWorld() until the next
navigation/reload.
