The notification box remains on the form until either: - the user closes it explicitly, or - the user edits the record, or - the form view is refreshed (switch to another record, or refresh form). Add a method `once` to `EventDispatcherMixin`, as it is convenient. Make `FormView` trigger events `to_view_mode` and `to_edit_mode`.
