This is really minor and probably did not caused any issues in real life
Views is trying to fetch the base fields of relationship tables for proper automatic relationship.
For header/footer/empty though $form_state['type'] is 'header', even the actual type which
should be passed into the function is 'area'.
$base_fields = views_fetch_fields($base, $form_state['type'], $view->display_handler->useGroupBy());
To be able to fix that it should do similar things to views_ui_add_item_form, so call ViewExecutable::viewHandlerTypes and check for the type.
$types = ViewUI::viewsHandlerTypes();
$ltitle = $types[$type]['ltitle'];
$section = $types[$type]['plural'];
if (!empty($types[$type]['type'])) {
$type = $types[$type]['type'];
}
