This bug workaround will primary benefit larger Jira instances with many Epics.
When creating bugs or feature requests, there is an Epic Link field letting you connect your new issue to an existing Epic.
Have you noticed that is showing rather a lot of Epics in the Epic Link drop-down? In fact, that it is showing Epics that are resolved, despite the Show done epics
checkbox being unchecked?
This is a bug.
