Field Title length should match Webform limit (255 characters) instead of 128 limit

I see that issue with maxlength property is resolved here: http://drupal.org/node/1816212, but I can't find anywhere where to set maxlength... Anyway as I understood correctly - there is some field where I can set maxlength for text field - it's not necessary - just set maxlength (in code) to database field limit which is 255 chars.
Previous paragraph is not relevant to this issue.
I am talking here about field Title (see attached screenshot) which can be only 128 chars long when I create it with Form Builder. I found that in "form_builder.properties.inc" function "form_builder_property_title_form" (line 72) $form['title'] has no property '#maxlength'. By studying Drupal form API I noticed that '#maxlength' default is 128. I think if you do not set it, it defaults to 128. I made a dirty module hack and added line '#maxlength' => 255 to $form['title'] array and I can set field title 255 chars long now.
Long story short:
change "form_builder.properties.inc" function:

/**
 * Configuration form for the "title" property.
 */
function form_builder_property_title_form(&$form_state, $form_type, $element, $property) {
  $form = array();

  $form['title'] = array(
    '#title' => t('Title'),
    '#type' => 'textfield',
    '#default_value' => $element['#title'],
    '#required' => TRUE,
    '#weight' => -10,
  );

  return $form;
}

to:

/**
 * Configuration form for the "title" property.
 */
function form_builder_property_title_form(&$form_state, $form_type, $element, $property) {
  $form = array();

  $form['title'] = array(
    '#title' => t('Title'),
    '#type' => 'textfield',
    '#default_value' => $element['#title'],
    '#maxlength' => 255,
    '#required' => TRUE,
    '#weight' => -10,
  );

  return $form;
}
