Adding minecraft:cannot_be_attacked does not stop already attacking mobs from attacking

Summary:

Adding minecraft:cannot_be_attacked does not stop already attacking mobs from attacking

Impact:

A primary use we have for this component are mobs that "faint" instead of dying like in our Craftee Companion project. Because the mob never really dies, vanilla mobs do not stop targeting and attacking them even though we want the game to consider them dead. We have used workarounds for this in the past, but this component presents a great opportunity for us to achieve this effect officially, if it correctly stopped mobs who were already targeting our custom ones.
