Light-emitting blocks (including end portal frames) ignore ambient occlusion/smooth lighting, regardless of model's settings

End portal frames did not have AO enabled. However, the line " "ambientocclusion": false " is not in its model mesh file. The default for this argument is "true" so it seems that AO is somehow not being applied. (even adding " "ambientocclusion": true " doesn't work)

This affects all light sources as well. When a light source is set to use another block's model, the ambient occlusion setting is not inherited.
