How to reproduce:
1. Open the attached “IN-90920.zip” project
2. Open the “MeshInstancing” scene
3. Ensure Game View is in focus
4. Open “Assets/Shaders/MeshInstancing.shader”
5. Cause a compilation error by adding random text to the “Test” Shader Pass (added “asd” at line 58 in testing)
6. Notice the “Keyword Space Mismatch” errors in the Console window

Expected result: Only expected shader errors appear
Actual result: A large number of unexpected “Keyword space mismatch” errors are constantly appearing

Reproducible in: 6000.0.36f1, 6000.1.0b4, 6000.2.0a1
Could not test with: 2022.3.57 (“missing ‘RayTracingShader’ namespace” errors)

Reproducible on: Windows 11
Not reproducible on: No other environments tested
