The breeze's model is set up so that the emissive parts are on its eyebrows and an 8x1x1 box inside of its head where the eyes are located, which can be an inconvenience for resource pack makers who want to change the location of the eyes on the breeze's texture.
I propose a change so that the glowing parts of the breeze's model are determined by a seperate "eyes" texture that can be applied across the entire model, like how every other entity with emissive pixels in its texture already does it (spiders, endermen, ender dragons, phantoms, wardens).
Can confirm. I would say it's noteworthy that all other mobs in the game which have emissive eyes seperate the base layer and the emissive eye layer into two different textures to allow for more dynamic adjustability of the model, and texture. The enderman, spider, phantom, and ender dragon all do this.
