[macOS] Editor crashes when making changes to Prefab script components, which were previously Missing (Mono Script)

Scene Management

-

How to reproduce:
1. Open user-submitted project (CombinedTutorials.zip)
2. Open the Common/Scenes/Main scene
3. Expand the 'Hero' GameObject and select 'CharacterInventory'
4. Click the circle icon near the Missing (Mono Script) and select 'CharacterInventory' script
5. Expand 'Inventory Display Slots' array and change its size(e.g. to 15)
6. Click the circle icon near the 'Inventory Display Holder' and select any Prefab

Expected result: the Editor does not crash
Actual result: the Editor crashes

Reproducible with: 2019.3.0b1, 2019.4.1f1, 2020.1.0b13, 2020.2.0a15
Not reproducible with: 2018.4.23f1, 2019.3.0a12

Notes:
Removing the missing Component instead of reselecting it in step 4 prevents the crash from occurring
