The bug

Zombified Piglins (Zombie Pigmen) get angry when hit in Creative mode and remain angry when switching to Survival mode afterwards.

Expected would be that hitting a Zombified Piglin in Creative mode should not make them angry.

Reproduction steps

1. Spawn a Zombified Piglin
2. If not already, change to Survival or Adventure mode
   The Zombified Piglin does not attack you
3. Switch to Creative, and hit the Zombified Piglin
4. Switch back to Survival or Adventure (e.g. using F3 + F4)
   Now the Zombified Piglin attacks you, even though you were in Creative mode when you hit it
