Steps to reproduce:
1. Open the “14.0.3 SG Shader Error” project
2. Select the “New Shader Graph” shader
3. Observe the shader “Errors” property in the Inspector window

Expected result: Shows no warnings
Actual result: Shows warning “gradient instruction used in a loop with varying iteration, partial derivatives may have undefined value” in LightCookieInput.hlsl:102

Reproducible with: 2020.3.42f1, 2021.3.14f1, 2022.1.23f1, 2022.2.0f1, 2023.1.0a19
Not reproducible with: 2023.1.0a20

Reproduced on: macOS Monterey 12.2 (Intel)

Note: The previous warning message is gone in 2023.1.0a20, but two other warnings appeared:
“gradient instruction used in a loop with varying iteration, partial derivatives may have undefined value” in GlobalIllumination.hlsl:205
“gradient instruction used in a loop with varying iteration, partial derivatives may have undefined value” in GlobalIllumination.hlsl:206
