"shade: false" is ignored by item models

The bug

Item models completely ignore "shade: false" even though they do not ignore other specifications such as the recently added “light_emission"

How to Reproduce

This bug is easily replicable by holding a Calibrated Sculk Sensor in the player's hand and moving the camera in any direction, the models for this block have two "shade: false" cubes that form the amethyst shard on it
