The bug
When Pillagers are in water and when they have a target, they do not move anymore.
This can break raids and make them not very fun.
How to reproduce
Start a raid
Push Pillagers into a pool of water and watch what happens
Or else: you can just spawn a Pillager with an egg directly in water and see what happens
Example
Here is an example in video:
