states.js not working for form type "item" as ID is not added

After I changed my admin theme to bootstrap, my forms #states stopped working. When I looked into it I found that ID selector was not added to the form element "item". I have used form type "item" to wrap around some form elements and to display/hide those elements based on a radio button. So the #markup is empty.

bootstrap_form_element in form-element.fun.php does not add wrapper id if #markup is empty.

  // Add wrapper ID for 'item' type.
  if ($type && $type === 'item' && !empty($element['#markup']) && !empty($element['#id'])) {
    $wrapper_attributes['id'] = $element['#id'];
  }

I checked in includes/forms.inc, there it checks only for isset before adding ID.

// Add element #id for #type 'item'.
  if (isset($element['#markup']) && !empty($element['#id'])) {
    $attributes['id'] = $element['#id'];
  }

Is there any reason why we check if markup is empty before adding wrapper ID? Can we patch it with isset?
