New description:

 Similar to #29660 and resolved for a lot of things in [54496],
 get_body_class() and wp_list_pages() throw many PHP warnings due to
 missing post objects when the request is singular, but no post is located.

 These include in `get_body_class()`:
 > E_WARNING: Attempt to read property "ID" on null in wp-includes/post-
 template.php:676
 > E_WARNING: Attempt to read property "post_type" on null in wp-includes
 /post-template.php:677

 and in `wp_list_pages()`:
 > E_WARNING: Attempt to read property "post_type" on null in wp-includes
 /post-template.php:1356

 and again in `feed_links_extra()`:
 > E_WARNING: Attempt to read property "comment_count" on null in wp-
 includes/general-template.php:3351
 > E_WARNING: Attempt to read property "ID" on null in wp-includes/general-
 template.php:3359
 (although in this case, it's not get_queried_object(), just an expectation
 of `get_post(0)` working, which is effectively the same thing)
