Reloading a Shader Graph window incorrectly marks the asset as dirty

Steps to reproduce:

1. Create a new 2D URP project
2. In the Project window, right-click and navigate to Create > Shader Graph > From Template ...
3. In the newly opened window, select "2D Sprite Lit" and click "Create"
4. Open the asset in the Shader Graph window by double-clicking it
5. Click the kebab (three dots) icon in the top right of the Shader Graph window
6. Select "Reload window"
7. Observe that the Shader Graph becomes dirty (an asterisk * appears on the tab name)
8. Click the kebab icon and select "Reload window" again
9. A pop-up will appear asking if you want to save the unsaved changes
10. Click "Discard Changes"
11. Observe the Shader Graph window once it reloads

Actual results: The Shader Graph becomes dirty merely by reloading the window.

Expected results: Reloading a window should only refresh the editor UI; it should not modify the asset or mark it as dirty.

Reproducible with versions: 6000.3.0a2, 6000.5.0b2

Can’t test with versions: 6000.3.0a1 ("From Template ..." is not implemented yet)

Tested on (OS): macOS Sequoia 15.7.4 (M1)

Notes:

1. Does not reproduce when creating URP > Lit Shader Graph
2. Does not reproduce when reopening the project and performing the steps on already created assets.
