Comment (by dglingren):

 Further investigation reveals that this is caused by obsolete code in my
 plugin, Media Library Assistant. WordPress 5.3 added a position argument
 to the add_submenu_page() function and my code did not keep up.

 In any case, the get_admin_page_title() function can return an empty
 result and testing for this in admin-header.php would avoid the deprecated
 message.
