“Metal: Shader[HDRP/Unlit]” warnings are constantly thrown after trying to restructure Particle System Prefab

Reproduction steps:
1. Create a new High Definition 3D project
2. GameObject > Effects > Particle System
3. Create another Particle System GameObject under newly created Particle System GameObject
4. Drag and drop Parent Particle System GameObject to the project window to create a Prefab
5. Move Child Particle System GameObject to the same level as Parent Particle System GameObject
6. Press “Open Prefab” button in “Cannot restructure Prefab instance” pop-up
7. Observe the Console

Actual result: “Metal: Shader[HDRP/Unlit]: Pixel format [MTLPixelFormatRGBA8Unorm_sRGB] of texture [UnityDefault2DArray] bound at index 6 is incompatible with texture parameter [uint _StencilTexture]. Compatible types [float, half]” warnings are constantly thrown
Expected result: No errors or warnings are thrown

Reproducible with: 6000.4.0a5, 6000.4.9f1, 6000.5.0b10, 6000.6.0a5
Not reproducible with: 6000.0.76f1, 6000.3.16f1, 6000.4.0a4

Reproduced on: macOS Tahoe 26.4 (M4)
