Zombified Piglin model missing an ear

I have found an anomaly on the Zombified Piglin 3D model.
I didn't know if it's a bug or if it's intentional, but i think it must be reported.

I have noticed than, on the zombified piglin model, one side of the head didn't have an ear, while the other side have one, and apparently, it's the case for all zombified piglins.
