Redundant options key

In \Drupal\entity_reference_layout\Plugin\Field\FieldWidget\EntityReferenceLayoutWidget::prepareFormState() i found a duplicated 'options' array key, that could be removed.

        $layout_properties = [
          'options' => [],
          'options' => isset($item->options) ? $item->options : [],
          'config' => !empty($item->config) ? $item->config : [],
          'region' => isset($item->region) ? $item->region : '',
          'layout' => isset($item->layout) ? $item->layout : '',
          'entity_bundle' => $item->entity->bundle(),
          'parent' => -1,
        ];
