Don't allow 0-sized views to be focused.
These zero-sized views tend to make keyboard navigation
difficult for users since focus "disappears" sometimes.
This takes a best-effort approach for focus requested
prior to layout: If a View hasn't been laid-out and is
asked to take focus, it will act as though this size
constraint doesn't exist. Then, upon layout, it will
defocus itself if it still has no size.
