Privatemsg overwrites page title for custom code. How do I correct it?

Question

I am using Private message as PHP in a block on the node of a page so that a person can contact the node author without having to leave the page. Here is the code:

$node = menu_get_object();
if ($node->uid != 0) {
module_load_include('pages.inc','privatemsg');
  $recipients = $node->uid;
print "<div>Contact " . $node->name ." about this post.</div>";
  $subject = $node->title ." question.";
  print drupal_render(drupal_get_form('privatemsg_new', $recipients, $subject));
}

However, Private message hijacks the title of the entire page, and now every single node value is 'Write so-and-so' a new message, instead of what the page title should actually be.

Thoughts on how to correct this?

You can check out what's happening here on the test server:

I guess the private message form sets the title directly. A simple way round it might be to cache the current title before you render the form, then set it back again afterwards:

$stored_title = drupal_set_title();
print drupal_render(drupal_get_form('privatemsg_new', $recipients, $subject));
drupal_set_title($stored_title);
