  /**
   * Gets the current value of a #select element, from within a form constructor function.
   *
   * This function is intended for use in highly dynamic forms (in particular the
   * add view wizard) which are rebuilt in different ways depending on which
   * triggering element (AJAX or otherwise) was most recently fired. For example,
   * sometimes it is necessary to decide how to build one dynamic form element
   * based on the value of a different dynamic form element that may not have
   * even been present on the form the last time it was submitted. This function
   * takes care of resolving those conflicts and gives you the proper current
   * value of the requested #select element.
   *
   * By necessity, this function sometimes uses non-validated user input from
   * FormState::$input in making its determination. Although it performs some
   * minor validation of its own, it is not complete. The intention is that the
   * return value of this function should only be used to help decide how to
   * build the current form the next time it is reloaded, not to be saved as if
   * it had gone through the normal, final form validation process. Do NOT use
   * the results of this function for any other purpose besides deciding how to
   * build the next version of the form.
   *
   * @param \Drupal\Core\Form\FormStateInterface $form_state
   *   The current state of the form.
   * @param $parents
   *   An array of parent keys that point to the part of the submitted form
   *   values that are expected to contain the element's value (in the case where
   *   this form element was actually submitted). In a simple case (assuming
   *   #tree is TRUE throughout the form), if the select element is located in
   *   $form['wrapper']['select'], so that the submitted form values would
   *   normally be found in $form_state->getValue(array('wrapper', 'select')),
   *   you would pass array('wrapper', 'select') for this parameter.
   * @param $default_value
   *   The default value to return if the #select element does not currently have
   *   a proper value set based on the submitted input.
   * @param $element
   *   An array representing the current version of the #select element within
   *   the form.
   *
   * @return
   *   The current value of the #select element. A common use for this is to feed
   *   it back into $element['#default_value'] so that the form will be rendered
   *   with the correct value selected.
