Object Picker scrolls incorrectly depending on which asset was selected previously when in grid view

Steps to reproduce:

1. Create and open a new URP project
2. In Project tab, find the asset referenced in the Volume component
3. Duplicate the asset many times (~60 times, for reproduction showcase)
4. Select the "Global Volume" GameObject
5. Open the "Volume" component Object Picker
6. Make the icon size the largest (grid view) in the Object Picker (reproducible with any size)
7. Change the Asset reference to the ~20th item
8. Observe the scrollbar position
9. Close and open the same Object Picker again
10. Observe the scrollbar position

Actual results: The scrollbar is much further down than the selected item, and the selected item is not in view

Expected results: The scrollbar is exactly at the same point where the selected item was previously

Reproducible with versions: 6000.2.0a8 (6bc6fbc26ac6), 6000.3.16f1, 6000.4.9f1, 6000.5.0b10, 6000.6.0a6

Not reproducible with versions: 6000.0.76f1, 6000.2.0a7

Tested on (OS): Windows 11 Pro (25H2)

Notes:

• Not reproducible when available references are in a list form in the Object Picker
• Reproducible with any Object Picker instance where a lot of references are displayed (easiest to observe when there are >30 assets available in the Object Picker)
