Endermen can teleport away during death animation

Endermen teleport away from where they die, meaning that their drops (XP, Enderpearls) can end up some distance away from the player.

Although they may teleport when they receive damage, when they actually die they should stay in the same place.

Steps to Reproduce:

• Spawn some endermen in the overworld during daytime, since they're more likely to teleport in these conditions
• Attack endermen
• Sometimes an enderman will teleport during its death animation, causing its items & xp to drop at the location it teleports to.
