Minecart, Minecart with Chest/TNT/Hopper/Command Block have their textures rotated when turning a different direction on a rail/corner rail.

When you have a minecart, minecart with chest, tnt, hopper, and/or command block on rails/corner rails and they go off, the textures on the blocks change/rotate when turning a different direction.

_rplatham edit: There seems to be a more generic case for this, since in MCPE-13167 the chest in the minecart flips the direction the chest is facing when the minecart with chests changes direction on the rails.
