Shulkers get extremely little pushed when hurt

Tested with mods, but still...

The bug

When a Shulker gets hurt, while he dosen't look like being pushed, it's extremely extremely extremely extremely extremely by 1,000,000,000,000,000 pushed.

How to reproduce (Modded)

1. Get MCreator
2. Make a Spike-like block that deals massive damage to entitys.
3. Put a Shulker next to it.
4. It dies.
5. Put a Shulker away from it.
6. It dosen't die.
   Notice: The Shulker dosen't catch on fire if you do the same but with fire. Sorry if its Invalid, Won't Fix or Works as Intended but you should check it.
