Versions ("Latest" is NOT a version):

• Minecraft: 1.16.5
• Forge: 36.0.43
• Gaia Dimension: 1.3.2
• Client log: N/A

To Reproduce:

1. Place a beam in a top-slab like position (tested with stonebrick)
2. Place a second beam in the same block in the lower position (so like a stair block missing the middle part)

Describe the bug
When placed in this configuration the top beam drops so the two beams appear as a bottom slab, and the face where the top beam was becomes an x-ray glitch

Additional context
Discovered on the tf testing server.

I'm a dumb, moved this to the correct github
