      case 'option':
        transaction.getReactMountReady().enqueue(
          optionPostMount,
          this
        );
        break;
      default:
        if (typeof props.onClick === 'function') {
          transaction.getReactMountReady().enqueue(
            trapClickOnNonInteractiveElement,
            this
          );
        }
        break;
    }
    return mountImage;
  },
