Sheep/Ghast spawn egg textures are broken

In Third Person View, looking up while holding a ghast/sheep spawn egg will display a "white spawn egg". The sheep spawn egg's pink spots aren't shown above the players arm, and the ghast spawn egg's dots are a lot lighter. This only affects ghast and sheep spawn eggs, other white-related spawn eggs aren't affected. Thi can be seen by an item frame/armor stand, even the offhand of a vindicator.
