Auto-save of epic description to local storage
internal customer since JamesR and other folks at GitLab have said that they lose data when typing the description in an epic and there's a problem and the tab closes and the data is lost.
- Content in an epic description is not saved to local storage currently.
- In other places in GitLab (issue/mr descriptions, comment textboxes), this is currently supported. So would be nice to get parity here.
