User doesn't get notified when assigned ticket if user is a customer and agent in the same organization

Summary

If agents are registered as customers and one of them opens a request shared with the rest of the organization. The default assignee doesn't get notified being assigned a ticket if we disable Organization added notifications from the project settings although JIRA notification schema is set to notify assignee.

Environment

• JIRA Service Desk with agent are also customers within same organisation.

Steps to Reproduce

1. Create an Organization in JIRA Service Desk.
2. Set a default assignee as one of the agents who is also a customer in the same organization.
3. Add the agents as customers in this Organization.
4. Disable Organization added from Customer Organization to avoid excessive notifications to users who aren't involved.
5. Create a request from the customer portal that is shared with the organization.

Expected Results

• Assignee gets notification being assigned a new ticket.

Actual Results

No notification is sent to the assignee

Workaround

• remove the agents from the same organization as the customer.
  OR
• enable JIRA notifications to customers at Settings - Application - JIRA Service desk Configuration - Yes, send customers both Jira Service Desk and Jira notifications. But this will cause that the reporter will get two notifications for both JIRA and JSD.
