      * Special case: Absolute paths.
      *
      * - add_submenu_page() applies plugin_basename() to the menu slug, so we don't need to worry about plugin
      * paths. However, absolute paths that *don't* point point to the plugins directory can be a problem.
      *
      * - Due to a known PHP bug, certain invalid paths can crash PHP. See self::is_safe_to_append().
      *
      * - WP 3.9.2 and 4.0+ unintentionally break menu URLs like "foo.php?page=c:\a\b.php" because esc_url()
      * interprets the part before the colon as an invalid protocol. As a result, such links have an empty URL
      * on Windows (but they might still work on other OS).
      *
      * - Recent versions of WP won't let you load a PHP file from outside the plugins and mu-plugins directories
      * with "admin.php?page=filename". See the validate_file() call in /wp-admin/admin.php. However, such filenames
      * can still be used as unique slugs for menus with hook callbacks, so we shouldn't reject them outright.
      * Related: https://core.trac.wordpress.org/ticket/10011

      * paths. However, absolute paths that *don't* point point to the plugins directory can be a problem.
      *
      * - If we blindly append $pageFile to another path, we'll get something like "C:\a\b/wp-admin/C:\c\d.php".
      * PHP 5.2.5 has a known bug where calling file_exists() on that kind of an invalid filename will cause
      * a timeout and a crash in some configurations. See: https://bugs.php.net/bug.php?id=44412
      *
      * - WP 3.9.2 and 4.0+ unintentionally break menu URLs like "foo.php?page=c:\a\b.php" because esc_url()
      * interprets the part before the colon as an invalid protocol. As a result, such links have an empty URL
      * on Windows (but they might still work on other OS).
      *
      * - Recent versions of WP won't let you load a PHP file from outside the plugins and mu-plugins directories
      * with "admin.php?page=filename". See the validate_file() call in /wp-admin/admin.php. However, such filenames
      * can still be used as unique slugs for menus with hook callbacks, so we shouldn't reject them outright.
