How to reproduce:
1. Create a new project with the default 3D template
2. Create an empty Script with the DisallowMultipleComponent attribute
3. Create a few original Prefabs
4. Add the previously created Script on one of the Prefabs
5. Set up Collaborate
6. Publish the initial project
7. In the Project Window, select all of the previously created Prefabs (including the one with the added Script)
8. Through the Component->Scripts tab, add the Script
9. Close the error prompt
10. Inspect the Collaborate Window

Expected result: Changes are listed
Actual result: Changes are not listed

Reproducible with: 1.3.9, 2.1.0-preview.6 (2020.3.1f1, 2021.1.0b12, 2021.2.0a9)
Not reproducible with: 1.2.16 (2018.4.33f1, 2019.4.22f1)

Note:
- Selecting the Prefabs individually in the Project Window, updates them in the Collaborate Window
- Sometimes the issue is not consistent, the regression might not be correct
