Editor crashes in GetPrefabHandle when deselecting a Prefab without a prefab contents root

Scene Management

-

How to reproduce:
1. Open user-submitted project (forge.zip)
2. Select Tools > ProBuilder > Editors > New Poly Shape
3. Without deselecting the 'New Game Object' in the Hierarchy window drag it into the Project window
4. Deselect the created Prefab

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

Reproducible with: 2018.4.9f1, 2018.4.18f1, 2019.3.3f1, 2020.1.0a25, 2020.2.0a1
Not reproducible with: 2018.4.8f1
Could not test with: 2017.4.37f1(ProBuilder package unavailable)

Notes:
In 2018.4.8f1 and earlier versions opening the Prefab and deselecting the New Game Object a pop-up is thrown instead and no crash occurs:
"Error: The Prefab contents root has been deleted"

  1. Resolution Note (fix version 2020.2):
