Cannot confirm. Maybe the Golem landed on a weird pace when you tried it. But then it has nothing to do with the Zombie.

Can't either, but attacking the iron golem, it doesn't take any knockback.

I added a video showing the bug. The fact that iron golems take no knockback is intended as far as I know.

I think it has something to do how the Zombie flies after the iron golem punched it. When you're standing on the ground, it happens more rarely.
Happens sometimes, can now confirm.

Seems to be fixed for 1.13-pre6. Can someone else confirm this?
