Overriding theme_forward_page

The only way to successfully override theme_forward_page is to change line 494 in forward.module from:

return drupal_get_form('forward_form', $form_state['values']['path'], $node->title)

to:

return theme('forward_page', drupal_get_form('forward_form', $form_state['values']['path'], $node->title), $node);

Is this a bug?
