Severe z-fighting inside snow golem

I know z-fighting inside entities' heads has always been an issue, but this particular case is severe to the point where I think it needs to be fixed.
Looking down inside of a snow golem's head while moving the cursor results in a psychedelic flash of orange, white and black which is visually repulsive to say the least. I don't know how long this particular issue has been around, but I hope it'll be fixed soon considering just moving certain parts of the entity down .001 blocks visually should do the trick.

As of an unknown version the z-fighting is simply a white and gray.
