How to reproduce:
1. Open the user's attached project
2. Open Window > Example Window
3. Select the last element in the ListView
4. Drag the selected element to the top of the list
5. Observe the Console

Expected result: No visible errors present
Actual result: ArgumentOutOfRangeException gets thrown in the Console

Reproducible with: 2021.1.0a8, 2021.1.0b11, 2021.2.0a8
Not reproducible with: 2020.1.17f1, 2020.2.7f1, 2020.3.0f1, 2021.1.0a7
Cannot test with: 2018.4.32f1 (the ListView is not supported), 2019.4.22f1 (the ListView doesn't have the 'reorderable' property)
