 Hi there!

 This issue still happens if we use the ticket author's suggested code
 snippet.

 {{{#!php
 <?php
 echo count($wp_object_cache->cache['posts']);

 $query = new \WP_Query([
   'post_type' => 'post',
   'cache_results' => false,
   'posts_per_page' => 5,
   'ignore_sticky_posts' => true
 ]);

 echo '<br>' . count($wp_object_cache->cache['posts']);
 }}}


 `dev-feedback` added so we get more eyes on this issue and someone from
 core time will tackle this.
