Shadows are not present when using unity_SpriteColor and Alpha Clipping in Shader Graph

Reproduction steps:
1. Open the attached project "ReproProj"
2. Open the “/Assets/Scenes/SampleScene.unity” Scene
3. Observe that shadows are present in the Game view
4. Open the “/Assets/Sprite-Lit-Transparent.shadergraph“ by double-clicking in the Project window
5. In Graph Inspector, enable Alpha Clipping
6. Press CTRL + S to save
7. Observe the Game view

Expected result: Shadows exist and are not flickering
Actual result: Shadows are not present or appear to be flickering

Reproducible with: 6000.0.47f1, 6000.1.0b15, 6000.2.0a9
Could not test with: 2022.3.61f1 (Shader error in 'Shader Graphs/Master': undeclared identifier 'unity_SpriteColor' at /(336) (on d3d11))

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

Note:

• Reproducible when unity_SpriteColor * VertexColor is used with Alpha Clipping
