Minecart with Hopper when broken drops minecart and hopper, but minecart will still have name "Minecart with Hopper".

To reproduce: Place down Minecart with Hopper. Break. Will drop two items - a minecart and a hopper.

However, when you pick up the Minecart and mouseover, the item will be still named "Minecart with Hopper", despite only being a Minecart.
