Steps to reproduce:

1. Go to OAuth 2 Administration and create an OAuth 2 application
2. Configure some scopes for the application and save it.
3. Use a client (command line, Postman, Insomia, ...) to access the OAuth application which will create an entry in `Authorizations`
4. Go to `Authorizations` tab and click on `Revoke` button (or select many and click "Revoke Authorizations")
5. Go back to "Scopes" tab

EXPECTED RESULT: The scopes are still properly configured

ACTUAL RESULT: All scopes are removed (unselected) from the application

As a result, revoking access for just one client blocks all clients from accessing the application until the scopes are reconfigured.
