*Steps to reproduce:*
# Open a Unity URP Project
# Create a new Shader Graph via Create > Shader Graph > URP > Lit Shader Graph
# Open the Shader Graph asset by double clicking on it
# Ensure the Main Preview pane is visible (toggle the pane with the Main Preview button in the Shader Graph Window toolbar
# Click on the bottom right corner of the Main Preview pane to start resizing, and drag towards the bounds of the Shader Graph Window

*Actual results:* The Main Preview pane is resized past the bounds of the window. After resizing, clicking on the header of the Main Preview pane will snap the resized pane back to the Shader Graph Window.

If the Main Preview pane is resized large enough past the bounds of the window, then when snapping back it can cover the entire Shader Graph Window. This can make the Main Preview window completely unusable (the resize corner can be outside of the bounds of the screen and can not be accessed). The only option to continue to use Shader Graph is to disable the Main Preview pane and not re-enable it. There is seemingly no accessible way to reset its size.

*Expected results:* The Main Preview pane is not resized past the bounds of the window and is blocked by the edges of the window.

*Reproducible with versions:* 6000.0.23f1, 2022.3.50f1, 2021.3.44f1

*Not reproducible with versions:* - 

*Can’t test with versions:* - 

*Tested on (OS):* Windows 11

*Notes:* 
* The other panes in the Shader Graph Window (Blackboard and Graph Inspector) are limited by the bounds of the window and can not be resized past it. It is just the Main Preview pane that has this issue.
