Expected Behavior: Spectator players cannot affect the game, and creative players are not a target for mob aggression

Steps to Reproduce: 

1. Use command from my previous post: /summon minecraft:drowned ~ ~ ~ {HandItems:[ {id:trident,Count:1}

   ],Attributes:[\{Name:"zombie.spawn_reinforcements",Base:0f}],HandDropChances:[0f]}

2. change gamemode to creative
3. punch the drowned a few times
4. notice zombies pathfinding to player
5. change gamemode to spectator
6. repeat step 4
