[1.12.2] Two issues with IBakedModel

[Corey]

I have a custom IBakedModel that delegates all methods except for getQuads to the model that it replaces.  It works great aside from two issues:

1. The block break cracks do not render.  I've looked at other peoples' custom IBakedModels and it doesn't appear that they have any custom code to render this.  Is it supposed to render automatically?
2. When in item form (ie. in a player's hand) the depth buffer doesn't seem to work.  The different layers of the model render on top of each other.  I'll attach a screenshot for this one.

getQuads adds vertices for the block itself on the CUTOUT_MIPPED layer, and vertices for the fluids on the TRANSLUCENT layer.  Here's the underlying model:
