Label title_display default setting for Fieldset

When setting the default setting for the label display field on a Fieldset component, it is not possible to enable this field by default.
File: "webform/compontents/fieldset.inc"

function _webform_defaults_fieldset() {
  return array(
    'name' => '',
    'form_key' => NULL,
    'pid' => 0,
    'weight' => 0,
    'extra' => array(
      'title_display' => 1, // NOT WORKING
      'collapsible' => 0,
      'collapsed' => 0,
      'description' => '',
      'private' => FALSE,
    ),
  );
}

A change in the "includes/webform.components.inc" file makes this option possible:
Changes @ line 429:

if (webform_component_feature($component['type'], 'title_inline')) {
      $form['display']['title_display'] = array(
        '#type' => 'select',
        '#title' => t('Label display'),
        '#default_value' => !empty($component['extra']['title_display']) ? $component['extra']['title_display'] : 'before',
        '#options' => array(
          'before' => t('Above'),
          'inline' => t('Inline'),
          'none' => t('None'),
        ),
        '#description' => t('Determines the placement of the component\'s label.'),
      );
    }
    else {
      $form['display']['title_display'] = array(
        '#type' => 'checkbox',
        '#title' => t('Hide label'),
        '#default_value' => ($component['extra']['title_display'] === 'none' ? TRUE : FALSE),
        '#return_value' => 'none',
        '#description' => t('Do not display the label of this component.'),
      );
    }

Before:
'#default_value' => strcmp($component['extra']['title_display'], 'none') === 0,
After:
'#default_value' => ($component['extra']['title_display'] === 'none' ? TRUE : FALSE),

The before version does not work because it returns a "1" if true instead of a "TRUE" value that is needed.
