Steps to reproduce:

1. Create a URP project.
2. Assets > Create > Shader Graph > URP > Lit Shader Graph.
3. Open Shader Graph editor.
4. Press spacebar and search for 'Color', create a Color node.
5. Connect Color node Out (4) to Fragment Base Color (3).
6. Change the color in the Color node, observe the Main Preview as you make changes in the Color Picker.

Actual results: Preview color does not update, instead it shows as an unlit cyan color until the Color Picker is closed. It will flicker with every change of color, as if it is updating.

Expected results:  Preview color updates in real time. The docs say that this is the expected result here: [https://docs.unity3d.com/Packages/com.unity.shadergraph@17.0/manual/First-Shader-Graph.html#change-node-output]

Reproducible with versions: 6000.0.11f1, 2022.3.35f1, 2021.3.40f1

Tested on (OS): macOS Intel - Monterey 12.7.4

Notes:

• Tried waiting to see if the cyan will load into the correct color eventually, this did not happen. It will only update when the color picker is closed.
• There is no trouble with the material updating in real time in the Scene View if you are using Shader Graph properties.
