/**
* 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 array|string
* 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.

// the #limit_validation_errors property set to prevent unwanted errors
// elsewhere on the form. This means that the $form_state->getValues() array
// won't be complete. We could make it complete by adding each required part
