Following this announcement, I tried to understand why some of the epics would still be listed on the backlog view.
It appears that if a `Done` epic contains only `Realeased` (a.k.a. `Done`) stories, it does not show in the epic panel of the backlog view.
If the epic contains a single `Won't Do` story (another `Done` state in our configuration), the epic is shown in the epics panel of the backlog view.
Why is that? did we miss something in our setup?
