--------------------------+-----------------------------
 If in the comments.php template file we use wp_list_comments() with a
 parameter 'per_page', any changes made to comments_array Hook are omitted
 or reset.

 Steps to reproduce:
 1. Set the 'per_page' argument like this: wp_list_comments( [ 'per_page'
 => '20' ] );
 2. Add this line to functions.php: add_filter( 'comments_array',
 'array_reverse' );

 The line in functions.php will not take effect. But if you remove the
 'per_page' parameter, everything works and the comment order is reversed.
