Either minecart or entity riding the minecart don't align properly.

When entities go into minecarts, sometimes they clip into the ground or they can float above the minecart while still riding it.

Steps to reproduce:
1. Have an impulse command block with this code on a 10 tick clock

• execute at @e[type=villager,dz=-1,dx=-1,dy=1] run summon minecraft:minecart ^ ^ ^
  2. In front of the command block have a powered rail facing down like a ramp.
  3. place a villager 2 blocks above the rail falling onto the rail.
  4. The villager has a chance of being misaligned.
