Minecart from a Dispenser causes you to float

Dispensing a Minecart from a dispenser onto a track causes you to sit too high when you get into the cart. The minecart itself looks like it sits on the tracks correctly, but you float above the cart.

If you end up going into a tunnel 2 blocks high then your screen glitches into the 3rd block and you lose visuals, but you don't lose health or suffocate.

If you break the cart then manually place it back down everything works as normal.
