Problem

Editing the Assignee field triggers both issue assigned and issue updated events rather than only the issue assigned event.

Steps to Reproduce

• Remove the users on the issue assigned event on the notification scheme, leaving the issue updated event.
• Edit the Assignee field
• Flush the mail queue
• Wait for the notification event on your mailbox

Expected Behaviour

No email is sent, as issue assigned is not configured in the notification scheme

Actual Behaviour

Issue updated event is sent for the change

Workaround

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