Notice: Undefined index: name in webform_component_update() and others if $component['features]['title'] == FALSE

I'm going to add a title that is hidden as a workaround, but reporting to help with reducing possible notices.

This error is triggered twice on submission of the webform component, twice on insert, and probably on delete too, maybe. It may just be cast to an empty string on insert / update so it would just be a bung message instead.

drupal_set_message(t('Component %name deleted.', array('%name' => $component['name'])));

Notice: Undefined index: name in webform_component_update() (line 813 of sites\all\modules\webform\includes\webform.components.inc).

So this is an issue with webform_component_insert() / webform_component_update() / webform_component_edit_form_submit() / webform_component_delete_form_submit() maybe other functions.

The cut-down definition was:

function coastal_webform_component_info() {
  $component_info = array(
    'user_details' => array(
      'label' => t('User details'),
      'features' => array(
        'title' => FALSE,
        'title_display' => FALSE,
        'title_inline' => FALSE,
      ),
    ),
  );

  return $component_info;
}
