(Case 1323760) Alpha clip threshold not working properly in HDRP

When you create two meshes that have overlapping faces and set alpha threshold and alpha below the threshold on one, it’s not rendered properly with HDRP. I submitted a bug report about this with a small reproductible: ID: 1323760

I tested this on 2021.1.1f1 and 2021.1.0f1.

I already created a thread about this but in the wrong section, it appears I cannot move it.

EDIT: The issue is updated because it’s apparently inherent to Unity’s design.
