This problem wasn't fixed it occurs in 1.16.100. I added a video clip you can see it isn't in beta because there is no text at the top of the screen.
Edit: Oh no I'm stupid, I understand why its in the current version now, sorry 1.16.200.52 is the fixed beta version

I tested this and they have fights even when they aren't naturally spawned
Is this intentional game design or a bug?
I have this problem with my helmet...
