Comment (by Chouby):

 @joedolson [55971] will introduce a backward compatibility issue for
 [https://wpdirectory.net/search/01H3H71EAYNVQX8ER7R216PB3Q all plugins]
 extending `WP_List_Table` and overriding `get_sortable_columns()`.

 Indeed, these plugins do not provide all the keys expected in
 see https://github.com/WordPress/wordpress-
 develop/commit/09fb3ea03ec554fe2ede5fb65118ab64a751e1df#diff-
 cb86bbc65c5b0b668d8a1b1a8b46cbe90f86c22cad5cdaea26bb77a4f34e484fR1364
 {{{
 list( $orderby, $desc_first, $abbr, $orderby_text, $initial_order ) =
 $sortable[ $column_key ];
 }}}


 This results in the error `Undefined array key 2`
