 Steps to reproduce:
 - Create a page called "Blog", slug: blog. ID: 10 permalink:
 https://a.com/blog/
 - Go to WordPress->Settings->Reading-> Your homepage displays -> A static
 page -> Posts page -> set the previously created "Blog" page.
 - Call ->

 {{{#!php
 <?php
 var_dump(url_to_postid('https://a.com/blog/'));

 }}}

 **Result:** 0
 **Expected result:** 10


 The cause is that this query is not for a singular page, so
 $query->is_singular will return false.

 The following code would solve this issue:
 {{{#!php
 <?php
 // Do the query.
 // Do the query.
 $query = new \WP_Query($query);
 if (!empty($query->posts) && $query->is_singular) {
         return $query->post->ID;
 } else {
         if ($query->get_queried_object() instanceof WP_POST) {
                 return $query->queried_object_id;
         }

         return 0;
 }
 }}}
