How to reproduce:
1. Create a new project
2. Set the Project window slider to a non-default value (e.g. highest value)
3. Type 't:scene' into the search bar of the Project Window
4. Save the search and call it 'Test' (it should appear in the 'Favorites' hierarchy)
5. Select any folder under 'Assets' in the Project Window hierarchy
6. Set the Project window slider to a non-default value (e.g. lowest left)
7. Select the 'Test' search in the Favorites hierarchy (the slider value should return to the value set in step 2)
8. Change the value of the search bar from 't:scene' to any string
9. Observe the slider.

Expected result: The slider returns to the same value that was set in step 6
Actual result: The slider value doesn't change
