Comment:

 A `null` value for `$title` should indicate that a plugin is doing
 something wrong because `get_admin_page_title()` requires a string.

 However, #57579 proposed to change `strip_tags()` to
 `wp_strip_all_tags()`, which would convert `null` to an empty string and
 silence the error message.

 ----

 If you have a plugin that uses either `null` or an empty string as the
 first parameter of `add_submenu_page()`, I think that parameter should
 have been `'options.php'` instead (though
 [https://wordpress.org/support/topic/depricated-errors/ plugin authors
 would need to confirm whether it works correctly]).
