When You Kill the Ender Dragon with a Weapon/Item that will Kill it in One Hit, Ender Crystals will Still Send Healing Beams At It, Attempting to Heal it

Here is a command to see the bug in action:

/give @p minecraft:stone 1 0 {AttributeModifiers:[

{Operation:0,UUIDLeast:1,UUIDMost:1,Amount:1000,AttributeName:generic.attackDamage,Name:Stone}

],display:{Name:"Stone"}}
