The Bug:

Ravagers and their passengers sometimes randomly look at one another.

There is a mechanic within the game that allows entities to randomly look at other nearby entities under certain circumstances. For example, if you summon a panda and stand beside it, you would notice that it will eventually turn to face you and look in your direction for around three seconds before looking away. This is working as expected, but when ravagers have passengers, typically illagers, you would notice that both the ravager and the passenger will occasionally look at one another, which should not be the case. This results in bizarre head rotations of both entities which just seems quite odd. This behavior cannot be seen with other entities riding on top of one another therefore one would expect ravagers and their passengers to function in the same way.

Steps to Reproduce:

• Summon an evoker riding a ravager.

• /summon minecraft:ravager ~ ~ ~ {Passengers:[{id:"minecraft:evoker"}]}

• Stand a fair distance away from them and observe their behavior for around thirty seconds.
• Take note as to whether or not ravagers and their passengers sometimes randomly look at one another.

Observed Behavior:

Ravagers and their passengers sometimes randomly look at one another.

Expected Behavior:

Ravagers and their passengers would never randomly look at one another, following the behavior of other entities that have passengers such as zombies riding chickens.
