[Bug] Birch Trapdoor Error When Opened - Classic 3D (16x)

[pastyginger]

Birch trapdoors give a visual error when right-clicked.

- Minecraft Version: 1.18
- Classic 3D Version: v14.0
- Optifine Version: 1.18-OptiFine_HD_U_H3

Error occurs even with no other resource packs in the load order.

This error only seems to occur when the birch trapdoor in its "open" state is intersecting the protruding 3D pieces of a block. Error does not occur when the trapdoor is placed on top of a block, or when it is opened with no blocks behind it to intersect with.

Other trapdoors are unaffected.

EDIT: This is likely an error with the face culling. I've found a temporary fix for the problem by going into assets/minecraft/models/block/birch_trapdoor_open.json and deleting every instance of "cullface" in the code.
