Code

public static function addItems(array $form, FormStateInterface $form_state) {

  // During the form rebuild, formElement() will create field item widget
  // elements using re-indexed deltas, so clear out FormState::$input to
  // avoid a mismatch between old and new deltas. The rebuilt elements will
  // have #default_value set appropriately for the current state of the field,
  // so nothing is lost in doing this.
