Baby turtles take damage when pushed against ceiling

The bug

Baby turtles take (suffocation?) damage when pushed or moving against the ceiling. This is similar to MC-50367, but apparently not exactly the same problem since it looks like their eye level ends below their hitbox.

How to reproduce

1. Build an upwards bubble column (soulsand) with a solid block above (e.g. stone)
2. Spawn a baby turtle inside the bubble column
   → The turtle takes damage below the ceiling
