 As we all know - '''in 4.4.0, Fragment caching for comments was removed in
 favor of split queries.'''

 But in the `\wp-includes\widgets\class-wp-widget-recent-comments.php` line
 104 we have


 {{{
 // Prime cache for associated posts. (Prime post term cache if we need it
 for permalinks.)
 $post_ids = array_unique( wp_list_pluck( $comments, 'comment_post_ID' ) );
 _prime_post_caches( $post_ids, strpos( get_option( 'permalink_structure'
 ), '%category%' ), false );
 }}}

 I'm not sure what this code does but it is related to caching.

 DO we need to remove this code?
