Shader starts acting unexpectedly when SV_primitiveID is used in a Hull/Domain Shader

How to reproduce:

1. Open the “SV_PrimitiveIDBuggy.zip“ project
2. Open the “bug_primitiveid” Scene
3. Select the “Assets/ExampleCode/Unlit_NewUnlitShader.mat“
4. In the Inspector, increase the “Index Value“ from 0 to 1
5. Observe the Scene view

Actual result: Shader triangles form into a cube regardless of the SV_PrimitiveID value
Expected result: Shader triangles displaced by the value of SV_PrimitiveID

Reproducible in: 2023.1.0a1, 6000.0.64f1, 6000.3.1f1, 6000.4.0b1, 6000.5.0a3

Reproduced on: Windows 11 Pro (24H2)
