The bug
The polar bear does an attack animation, but it doesn't emit vibrations if it doesn't deal damage, despite being a clear motion. This happens because unlike all other mobs, polar bears need to take a certain amount of time to attack.
To Reproduce
/summon minecraft:polar_bear ~ ~ ~ {Attributes:[{Base:0.0d,Name:"minecraft:generic.attack_damage"}]}
