Fix Version/s: Minecraft 16w43a
The hitbox of any baby mob jumps to a different location inside the animal shortly after summoning it or spawning it with a spawn egg. That might lead to some suffocation, although it's not nearly as bad as MC-50367.
This affects all kind of smaller variants of an entity including small armor stands.
- Press F3 + B to make hitboxes visible
- Use the following command
→ The hitbox starts at the back of the baby animal, but then jumps into the middle.
