Fixed in Universal RP 7.1.6

To reproduce:
1. Open attached project "ShaderGraph_NormalsTest.zip"
2. Open "SampleScene.unity" scene
3. Observe that both objects look the same
4. Change from Windows Standalone to another platform

Expected result: both objects look the same
Actual result: an object with PBR graph material has different shading
