The tail and inside of the saddle on invisible camels will not render when viewed from certain angles

While messing around with camels I noticed that when viewing an invisible camel in spectator mode or when on the same time as them, a few 2D parts of their model will not render when viewed from certain perspectives.

The two texture mishaps I noticed is the inside of the saddle and the top side of the tail texture. This may just be an oversight, but I had also noticed this with the warden in MC-253461.
