Reproduction steps:
1. Open the attached project “TestProject”
2. Open the “Assets/Scenes/MainScene.unity” scene
3. Select “Assets/Materials/NegativeAlpha.mat”
4. In the Inspector Window change the “Surface Inputs/HeightCutoff” value to any negative and then to positive values
5. Observe the changes in the material height in the Inspector Preview Window, and the “Cube” GameObject in the Scene

Expected result: The “NegativeAlpha” material and “Cube” GameObject height updates to match the inputs
Actual result: The “NegativeAlpha” material and “Cube” GameObject height remain constant in both Inspector Preview Window and Scene View when negative values are inputted

Reproducible with: 14.0.3 (2022.2.0a16), 14.0.6 (2022.2.5f1), 15.0.3 (2023.1.0b1), 16.0.1 (2023.2.0a9)
