 `WP_Query` matches any post when query parameter `name` is an empty
 string.

 For example:

 {{{
 $query = new WP_Query([
   'name' => '',
   'post_type' => 'post',
   'posts_per_page' => 1,
 ]);

 var_dump($query->posts);
 }}}

 The same is true for `get_posts()` which uses `WP_Query` internally.

 This might be the intended behavior, but it's unintuitive and surprising.
 It can (did) cause a bug in user code that expects such a query to return
 no results.
