Missed width and height attributes for image formatter

There's a problem when you enter values in "The resolution to crop the image onto" and this patch.

I choose 110x110 for the output resolution under this setting "The resolution to crop the image onto", then upload a big picture (like 1024x620) and select a square of 500x500 (cropbox_width x cropbox_height)

This patch adds width and height attributes following (cropbox_width x cropbox_height) eg 500x500, but my pic is only 110x110 so it's zoomed from 110x110 to 500x500...

I believe it's image_dimensions that should be used :

/**
 * Implements hook_field_prepare_view().
 */
function imagefield_crop_field_prepare_view($entity_type, $entities, $field, $instances, $langcode, &$items) {
  // Before render of image, we should set actual width and height values to pass to image attributes.
  foreach ($items as &$item) {
    if ((!isset($item[0]['width']) || !isset($item[0]['height'])) && (isset($item[0]['image_dimensions']) && isset($item[0]['image_dimensions']['width']) && isset($item[0]['image_dimensions']['height']))) {
      $item[0]['width'] = $item[0]['image_dimensions']['width'];
      $item[0]['height'] = $item[0]['image_dimensions']['height'];
    }
  }
  image_field_prepare_view($entity_type, $entities, $field, $instances, $langcode, $items);
}
