I'm not quite sure what the right thing to do here is: it doesn't make sense to
always blow these away. The problem is that keeping this here would blow away
the opener that gets set when creating the new view in
RenderViewImpl::Initialize, since this bit runs /after/ the render view is
already initialized.

There are probably other things that this should guard, but I just made the
minimum logical change to get layout tests working.
