Illager Beast behaves strangely when ridden

 

The Bug

 

The Illager Beast constantly hesitates to move when a pillager is riding it, causing it to become much less of a threat. It only exhibits this behavior in pursuit mode.

 

How to Reproduce

 

Trigger a village raid and wait for an illager beast to spawn with a rider and place a villager at least 12 blocks away from it.
