The detail sheet looked its record up by the row's id. For an occurrence
that id carries a #date suffix and is not a key in the store, so `own` came
back undefined and the edit and delete buttons vanished on every recurring
row — and a save would have reached editEvent with an id it could not find
and quietly done nothing.
The suffix is deliberate: marks key off the occurrence so each time round
carries its own completion. There is still only one record to edit.
