Unable to delete feed with from /admin/content/feed with delete selected feeds action

At the moment, it is not possible to delete a feed entity.

When using the form on /admin/content/feed to delete a feed entity, it states 'Delete selected feeds was applied to 1 item.' but nothing actually happens.

After some deep debugging, I have found the cause.

The annotation for DeleteFeedDrupal\feeds\Plugin\Action\DeleteFeed uses the parameter

confirm_form_path

where in Drupal\system\Plugin\views\field\BulkForm, the viewsFormSubmit() method expects the parameter

confirm_form_route_name

e.g.

$operation_definition = $action->getPluginDefinition();
if (!empty($operation_definition['confirm_form_route_name'])) {
  $options = array(
    'query' => $this->getDestinationArray(),
  );
  $form_state->setRedirect($operation_definition['confirm_form_route_name'], array(), $options);
}

After changing the annotation to use confirm_form_route_name instead, it is now possible to delete feed entities as you do get redirected to the deletion confirm form.
