Code

public function settingsForm(array $form, FormStateInterface $form_state) {

  // Filter settings are nested inside "details". Due to the way the Form API
  // works, any time a property is explicitly specified, the default property
  // values are not included. It must be manually retrieved and set here.
  $form['#process'] = $this->elementInfo
    ->getInfoProperty('details', '#process', []);

  // Now, add the process to build the subform.
  $form['#process'][] = [
    $this,
    'processSubform',
  ];

  // If there's no filter format set, attempt to extract it from the form.
  if (!$this->filterFormat && ($formObject = $form_state
    ->getFormObject()) && $formObject instanceof EntityFormInterface && ($entity = $formObject
    ->getEntity()) && $entity instanceof FilterFormat) {

      ->setFilterFormat($entity);
  }
  return $form;
