Button-specific handlers are checked first. If none exist, the function falls back to form-level handlers.

Parameters

array $form: An associative array containing the structure of the form.

\Drupal\Core\Form\FormStateInterface $form_state: The current state of the form. If the user submitted the form by clicking a button with custom handler functions defined, those handlers will be stored here.
