Editing 'Epic Link' on an issue creates 2 change history entries and fires 2 'issue_updated' events

Summary

When you edit the 'Epic Link' on a software issue, you get 2 entries in the change history for this operation and 2 issue_updated events fire

1. Edit the 'Epic Link' in a JIRA Issue
2. Check the issue history

There is one entry in the issue history.

Notes

You can also install the 'Connect inspector' from https://developer.atlassian.com/static/connect/docs/latest/developing/frameworks-and-tools.html and check the duplicate events on edit.

This is quite likely to impact customers who have automations / add-ons which relies on the events in the issue history.
