Make PiP reentry state to use scale instead of size
Beforehand the state was using fixed size, which could be below minimum
size for a given screen size, e.g. after you fold/unfold the device.
This change makes it so that the bounds scale is used instead of size,
which makes the PiP size always align with PiP Size Spec after reentry.
