Issue description
When I use an alpha clip material for foliage, I expect it to behave like an opaque material, going through the opaque rendering pass, so it should not have Z-ordering issues in its pixels. However it looks like it does have that typical issue:
Steps to reproduce
Create a mesh made of two intersecting quads (or make two separate quads), typical setup for classic grass
Create a new StandardMaterial3D with transparency set to Alpha Clip and an albedo texture.
Assign the material to the mesh instances.
Observe they completely disappear with Vulkan errors. I assume that's a different issue. Close the scene and reopen it. Observe the clipping issue.

The MRP can no longer be opened in Alpha13. However Alpha Scissors no longer has this issue with z-order. There are other z-order issues in the pipeline and I'll open another ticket, but it's no longer present here.
