Editor loads for a long time when doing an Undo action in a large Shader Graph
Reproduction steps:
1. Open the attached "PROJECTFILE" project
2. Open the "Assets/ShaderGraph.shadergraph" file
3. Move any Node in the “ShaderGraph” window
4. Perform the Undo action (macOS: command+z, Windows: ctrl+z)
Expected result: The Undo action is performed without a long Editor loading time
Actual result: Editor starts to load and completes the Undo action after several minutes
Reproducible with: 2021.3.30f1, 2022.3.10f1, 2023.1.15f1, 2023.2.0b11, 2023.3.0a7
Reproducible on: macOS 13.6 (M1 Max)
Not reproducible on: No other environment tested
Note: With version 2023.1.15f1 the Undo action is performed quicker compared to the other mentioned versions

Resolution Note (fix version 2022.3.11f1):
We should see an order of magnitude improvement to undo/redo times. Unfortunately, the undo/redo performance is based on the size of the graph and not the action itself. On very large graphs, we still recommend breaking them down into subgraphs where appropriate.
