 In menu editor wp-admin/nav-menus.php in tab 'View all' if there is more
 than 50 pages/records with hierarchy there is wrong hierarchy render.

 As I'm found in wp-damin/includes/nav-menu.php on line 621 we have
 function wp_nav_menu_item_post_type_meta_box that select from database 50
 records and order it by name.
 There is no ordering by parent, so sometimes it takes records with parent
 from different set of data (because of limit to 50 records) and menu can't
 render proper hierarchy.
 Unfortunately changes only ordering fixing this bug only on first set of
 data. If on next set of data ie. first record starts with parent from
 first set it's still wrong hierarchy.
