changing a queue's sort order deletes any annotations associated with its nodes

After adding some annotations, if you then change the queue's sort order via the queue's View page (admin/content/nodequeue/%nodequeue/view/%subqueue), all the annotations associated with that queue's nodes get erased.

Nodequeue Annotate adds its annotations to nodequeue's nodequeue_nodes table and the nodequeue_save_subqueue_order() function clears out a subqueue's rows in that table when updating its sort order:

  // clear the queue and save the new positions
  db_query('DELETE FROM {nodequeue_nodes} WHERE sqid = %d', $sqid);
  foreach ($nodes as $pos => $node) {
    $args = array();
    if ($pos != 'r') {
      $positions[] = $pos;
      $placeholders = ' (%d, %d, %d, %d, %d)';
      $args = array($sqid, $qid, $node['nid'], $pos, $now);
    }

    if (!empty($args)) {
      $sql = 'INSERT INTO {nodequeue_nodes} (sqid, qid, nid, position, timestamp) VALUES '. $placeholders;
      db_query($sql, $args);
    }
  }
