Armor Stand with head of a player that is unspecified makes entities go crazy,

When summoning an armorstand with a head with no name (command below)

/summon ArmorStand ~ ~1 ~ {CustomNameVisible:1,NoBasePlate:1,CustomName:Toy Bonnie,ShowArms:1,Equipment:[{},{},{},{},{id:397,Damage:3,tag:{SkullOwner:""}}]}

Makes entity models teleport to you, disappear, and do random things.
