Thanks for the report, but I can't reproduce the problem, or I misunderstood the steps.
you already reproduced it fortunately, can you notice the noise between the overlaping part between the alpha and the cube?

I can confirm the problem.
Strange if this hasn't been reported before.
It might be a limitation, but I'm confirming it as a Bug for now.

I can also confirm this bug.
The product https://blendermarket.com/products/moss-biome-ground-scatter---3d-assetkit-pbr is heavily affacted by this bug.
Tested in Blender 3.1.2 and 3.2 Alpha.

I can also confirm this bug, Unable to take position pass or depth pass on objects with alpha maps(leaves), This is a very basic pass needed for all comp and its not working
Added subscriber: @jbverdier
I can confirm the bug, it's really annoying when building natural environments and rendering the mist or position pass.
To compare, Clarisse makes the clip map available in raytracing, maybe that would help as the noise doesn't seem to appear in eevee.
