Issue Summary

Deleting a synced group via the API removes group role assignment from Jira projects.

Steps to Reproduce

1. Push a group using user provisioning and wait until this group get synced to your site.
2. Go to your Jira Cloud instance and select a project, go to project setting and then people.
3. Hit add people, select the group that was just pushed and grant any role to this group.
4. Run the request DELETE /rest/api/3/group to delete this very group.
5. You will get an error message and a HTTP status 400. The groups are NOT deleted and this is expected as the groups are being synced via user provisioning.
6. Go back to the People tab in your Jira project and refresh the page

Expected Results

1. The group will still retain its role because the group was not deleted.

Actual Results

1. The group lost its role. This the expected behavior if the group is deleted, which is not the case here.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
