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

Steps to Reproduce

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

Expected Results

There is one entry in the issue history.

Actual Results

There are two entries 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.
