When a entity has the {NoAI:1} tag, it can still be pushed, collided with, and punched resulting in knockback.

When I give a mob or entity the

{NoAI:1}

tag, it doesn't move and it acts normal. But players can push it around and collide with it, so that it moves. This bug is really bad for mapmakers, so please try and fix it. Below if a video that shows me giving the villager NoAI and then moving it. Thanks <3
