ReorderableList out of bounds exeception

Quality of Life


There is a change of behavior between 2022.2a3 and 2022.2a4 which is leading to an out of range exception while trying to reach an element in elementHeightCallback of a reordable list.

Repro step:
- Open Repro project
- Open scene named "Repro"
- Click on the game object in the scene while inspector opened
- Observe the several C# exceptions

No exception

N.B.: It's also possible this code was using an undefined behavior of the ReordableList

  1. Resolution Note (fix version 2020.3):

    Fix for this issue available on Unity 2020.3.35f1 and above
