AlphaClipTreshold does not update after connecting nodes to Master's Alpha input if AlphaClipTreshold's initial value was <= 0

Package: Shader Graph


How to reproduce:
1. Create a new URP/HDRP project
2. Create a new PBR Graph
3. Set the AlphaClipTreshold value in the Master node to 0 or less
4. Create a Checkerboard node and connect it to the Master's Alpha input
5. Change the AlphaClipTreshold value

Expected result: The preview node changes revealing the cut-out checkerboard pattern
Actual result: The changes to the AlphaClipTreshold value are ignored

Reproducible with: 2018.4.17f1, 2019.3.1f1, 2020.1.0a23
Could not test with: 2017.4.37f1(No PackageManager)

Package versions tested: 4.10.0, 7.1.1, 7.2.0, 8.0.0

Workaround: Attaching a Vector1 node to AlphaClipTreshold. Alternatively, disconnecting the input from AlphaClipTreshold port, setting AlphaClipTreshold to > 0 and reconnecting the Alpha input

1. Reproducible with HDRP and URP
2. Reproducible on Mac(Tested with 2019.3.1f1 and SG 7.2.0)
3. Tested with Unlit and PBR graphs
