If the player attacks a zombified piglin, they will follow them as intended, though this will continue if the player switches to spectator mode

What I expected to happen was...:
After I turned into spectator, the zombified piglins should not have been able to see me and should have gone back to being neutral

What actually happened was...:
The zombified piglins continued to chase me in spectator mode, even though I should have been invisible

Steps to Reproduce:
1. Anger a zombified piglin in survival mode
2. Switch to spectator mode
