If an Event has no publications and the user looks at the tab Recordings->Events->"Event Details"->General, the tab is just empty.
The goal of this story is to put some reasonable placeholder text there in case that the Event has no publications, i.e. instead of just displaying nothing, say something like "This event has no publications".
Of course, i18n is supported.
The PR addressing this issue has been merged. I therefore resolve this issue as "Fixed and reviewed".
