views pagers not using ajax

In views (and maybe elsewhere) Ajax pagers only work if the class 'pager' is also in the class array with 'pagination' - in template.php: 600. :

    return '<h2 class="element-invisible">' . t('Pages') . '</h2>' . theme('item_list', array(
      'items' => $items,
      'attributes' => array('class' => array('pager', 'pagination')),
    ));

But it also messes up the padding so some css/scss like this fixes the extra padding added.

.item-list .pager li {
  padding: 0;
}

Cheers
