Additional context

this happens because the wrong ModelData gets passed to children of MultiPartBakedModel, the root ModelData gets saved in BlockRenderer#renderModel, then the model and its children are traversed by fabric api's emitBlockQuads which doesn't handle ModelData

the bug causes the CaffeineMC/sodium#2906 & Commoble/morered#26

[PepperCode1]

To properly fix this, Forgified FRAPI should add a ModelData stack to the RenderContext and push/pop it accordingly inside of MultipartBakedModelMixin before/after calling emitBlockQuads on a submodel. RenderContext.getModelData would then return the current top-most element of the stack so that VanillaModelEncoder uses the correct ModelData.
