Issue Summary

User received alert email notifications after viewing the alert on the web, but it is not part of the scheduled escalation or any other escalation policy, however is part of the responder team

Steps to Reproduce

1. Step 1
   Add a user A to a team that has an On-call schedule and escalation policies configured.
2. Step 2
   Set up the On-call schedule and escalation policies with conditions where User A can't won't be alerted user at that particular time.
3. Step 3
   Open the alert with user A to add the activity log view on the Web (Viewed on [web]) in the alert ticket.
4. Step 4
   Make sure there are no notification policies configured.
5. Step 5
   Close the alert using user B.

Expected Results

When the ticket is closed, since user A just viewed the alert on the web, and didn't take any action beforehand, or was added as a responder directly, user A shouldn't receive an email notification when the alert was closed.

As mentioned in the The alert notification flow documentation:
Alert state (Closed) - Result (Responders are not notified)

Actual Results

User A will receive an alert email notification when the ticket is closed.

Workaround

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