With our notification scheme when an issue gets commented, "All Watchers" and "Current Assignee" both get notified. The Reporter is not listed in the Issue Commented.
Then a user (User X) reports an issue, selects to watch it, and the issue is being worked and then gets a comment added to it by another developer.
User X does NOT receive any notification for that comment.
Is it possible that because user X is both a reporter and a watcher, that is why this User X doesn't receive any notification?
