Meta Box

rwmb_normalize_field does not seem to work with a clonable group subfield
i have tried it like this:

add_filter( 'rwmb_normalize_group_id_field', function($field) {
  foreach($field['fields'] as $f) {
    if ($f['id'] === 'text_id') {
      $f['readonly'] = true;
    }
  }
  return $field;
});

rwmb_normalize_field works with other fields that are not in a group

i hvae als tried rwmb_normalize_meta_box but no success
