Research direction

Start by reproducing the return transition on ShapeableImageView with 0dp padding on the listed Pixel 4 API 31 emulator, then compare it with the 1dp-padding video. Trace the ShapeableImageView transition and rendering entry points to identify the source of the black corners. Done means the return transition has no black corners with zero padding while existing padded behavior remains intact.
