When a reporter is also a collaborator, he/she should get both customer notifications and internal comments' notifications.

Summary

If a collaborator is the reporter on an issue and an internal comment is added to the issue, the reporter/collaborator will not receive the email notification.

Steps to Reproduce

1. Open an issue with an user that is also a collaborator or agent in the project.
2. Add an internal comment with another user.

Expected Results

The reporter should receive the notification as they are a collaborator/agent as well.

Actual Results

• The reporter doesn't receive any notifications about internal comments, even if the user is also the assignee.
• No actions triggered by the reporter are sent (any comments or transition done by the user in the agent side sends notification for the reporter).

Notes

If the reporter is changed, the old reporter will receive the notifications if set as watcher.

Considering the following scenario:

• Two users: user1, user2
• Both users are agents

This is the current behavior:

Assignee	Reporter	Commenter	Internal Comment	Notification	Expected?	Why?
any	user1	user1				According to the latest Managing service desk notifications docs: the customer should always receive notification when a comment is added to the request.
user1	user1	user1				They should receive the notification as per the same reason as above
user1	user1	user2
user1	user1	user2				User is considered as "customer" only and therefore doesn't receive notification for internal comment, even though he is also the agent.
user1	user2	user2
