Self shadowing occurs on Quad when using Shader Graph with Camera Direction related to Vertex Position

Reproduction steps:

1. Open the attached project "ReproProj"
2. Open the “/Assets/Unity/Scenes/SampleScene.unity” Scene
3. Enter the Play Mode
4. Observe the Quad in the middle

Expected result: Shadow is rendered on the Plane
Actual result: Shadow is rendered on the Quad

Reproducible with: 6000.0.73f1, 6000.3.14f1, 6000.4.4f1, 6000.5.0b5, 6000.6.0a3

Reproducible on:
Play Mode
Windows Standalone Player

Testing environment: Windows 10 Enterprise 21H2
Not reproducible on: No other environment tested

Notes:

• This issue also happens when using the Transformation Matrix - View/InverseView Node
• This issue also happens when writing HLSL code by using: GetCameraForwardWorldSpace() or UNITY_MATRIX_V

Workaround:

• Passing the Camera Direction (Camera.transform.forward) via a script to a shader parameter
