Endermen with NoAI still teleport when hit

Endermen with the "NoAI" tag set to 1 will still teleport depending on the action taken against them.

They will not teleport under sunlight, as expected.

They will teleport away if struck by a direct physical attack, but will reappear where they were originally struck.

They will teleport away if a projectile is aimed for them, but will not reappear where they teleported away from.

/summon Enderman ~ ~ ~ {NoAI:1}

EDIT: They no longer appear to teleport from physical damage (please let me know if this isn't the case for 14w32d+), but still does so from projectiles.
