1. The first time the player controls are are made visible,
there is no animation.
2. The first time the player controls are made visible, the
"select tracks" button isn't displayed. When tapping to
subsequently hide the player controls, the button briefly
becomes visible and then is hidden again. This bug is due
to state in StyledPlayerControlViewLayoutManager being
out of sync, resulting in StyledPlayerControlView's
onVisibilityChange not being called properly.
After this change both of these issues should be resolved.
