When Plex made the collection and only the read after it failed, the kept row had no members: the
title showed unticked in the collection it had just been added to, the collection empty, and the
name stayed in the field for a retry that could only be refused as taken. The seed's row now names
the collection (child_count 1), and the panel clears the field on that refusal as on success. Also
held: the panel's lines sit beside its list, and a keyboard Retry lands on the first row.
