Cause the icon drawables to animate automatically by calling setVisible

false and then true on the drawables. For an AnimationDrawable, this will
trigger the desired behavior of 'automatically' starting the animation,
which should have been working to begin with according to the intended
design of AnimationDrawable (see http://b/1878430 for my description of
my correspondence with Romain). For Donut we'll just do this to work
around it, but for a later release we need to decide a better story.
