I don't think the issue is pointing out hind vs front legs, but rather that the polar bear is playing it's attack animation when it isn't actually dealing any damage to the player.
The fact it stands on its hindlegs and slashes its front legs/claws is intentional, this animation has been this way intentionally since its addition (there's even been fixes related to it), it is not a bug.
