How to reproduce:
1. Create and open a new project
2. Open Shortcut Manager (Win: Edit > Shortcuts, Mac: Unity > Shortcuts)
3. Double-click the “Main Menu/Assets/Refresh” shortcut to enter edit mode
4. Click outside the Shortcut Manager window
5. Observe “Main Menu/Assets/Refresh” shortcut bind

Expected result: the shortcut bind is set back to the previous bind
Actual result: the shortcut bind is removed

Reproducible with: 2021.3.48f1, 2022.3.58f1, 6000.0.38f1, 6000.1.0b5, 6000.2.0a3

Reproducible on: macOS 15.3 (M1 Max), Windows 11
Not reproducible on: no other environments tested

Note: In case of the shortcut bind being a custom one, it is preferred that the shortcut is set back to the custom value, rather than being set to the Default bind.
