Before the 'epic-link' replaced with 'parent' change, in the backlog view, epics related to the selected versions only were highlighted.
After the change, on selecting any versions, there is no change is display of the epics in the next panel.
Currently on selecting any version, the parent/epics not related to he version are also displayed in the epic panel
As we can see in the above screenshot, version 2 is selected, but the last 2 epics in the epic panel are not a part of the version
