External Parameters not working

[ProBoulder]

What happened?
When external parameter is created and linked to a UV node input (e.g. UV bias), changing the parameter's value does not have any visible effect. Texture is not changed in node editor, nor in inspector (when update texture is called), nor when changed using script.

To Reproduce
Create a new static mixture graph, add UV node to the input of default noise. Create exposed parameter of type Vector3 and link it to a UV bias input of the UV node. Changing a exposed parameter has no effect.

Setup:

• OS: Windows 11
• Tested in Unity Version:2022.1.4f1, 2021.3.6f1, 2021.1.20f1
• Mixture Version [0.4.0]
• HDRP version 11
