The dropdown task story works for a required task. That’s interesting.

The required flag isn’t copied over from old-style dropdown tasks. https://github.com/zooniverse/front-end-monorepo/blob/0c7bab65eaba1959662293dc5e5235cd97e69d2f/packages/lib-classifier/src/plugins/tasks/dropdown-simple/models/helpers/legacyDropdownAdapter/legacyDropdownAdapter.js#L6-L13
