Use bounds in parent rather than bounds in screen.

When checking if a node represents a view that can take focus, check
if the node's bounds in its parent are empty rather than checking if
the node's bounds in the screen are empty. The latter are always
empty for nodes representing views that are scrolled off the screen.
