Invisible villagers and wandering traders can be seen by zombies

The bug

Zombies, husks, pillagers, illager beasts, and vindicators can attack invisible villagers and wandering traders (making wandering traders drinking an invisible potion pointless), this should not happen.

How to reproduce

1. Summon an invisible villager.

   /summon minecraft:villager ~ ~ ~ {ActiveEffects:[{Id:14,Duration:10000,Amplifier:0,ShowParticles:0b}]}

2. Spawn a zombie.
   →  The zombie attacks the invisible villager.
