Same applies for snowballs which also deal no damage. Do you have a source that this is unintended? After all the weak mob is still causing knockback.

It affect 19w46b as well and also with snowballs.

In 1.20

Punch a chicken on Easy difficulty 3 times, and then throw an Ender Pearl at it and it flashes red despite not taking damage/dying.
