protected FormErrorHandler::setElementErrorsFromFormState(array &$elements, FormStateInterface &$form_state)
Stores the errors of each element directly on the element.
We must provide a way for non-form functions to check the errors for a specific element. The most common usage of this is a #pre_render callback.
Parameters
array $elements: An associative array containing the structure of a form element.
\Drupal\Core\Form\FormStateInterface $form_state: The current state of the form.
