Gradient Stop actions aren't redone in Shadergraph when undoing the node's creation

Steps to reproduce:

1. Create and open a new URP project
2. Create 'Assets/Shadergraph/URP/Lit' shadergraph and open it
3. Create a Gradient node
4. Open the Gradient node and move any lower stop
5. Observe the change in the node in the Shadergraph window
6. Undo until the Gradient disappears (CTRL+Z)
7. Redo until nothing changes in the Shadergraph window
8. Observe the Gradient node

Actual results: Gradient remains with the default gradient

Expected results: Gradient stop returns to its state before step 5
