New description:

 I have a multisite network with CPTs that are registered individually by
 subsite.
 The main site provides an overview of these, using
 {{{
 get_permalink( $post->ID );
 }}}
 to link to the pretty permalink location in each subsite.

 After the introduction of
 {{{
 wp_force_plain_post_permalink()
 }}}
 in WP 5.7.0

 #52373 #5272


 **get_permalink()** returns plain permalinks due to failing to pass the
 test in **wp_force_plain_post_permalink()**:


 {{{
         $post_type_obj   = get_post_type_object( get_post_type( $post ) );
 }}}

 **get_post_type_object()** returns null, as the CPT is not present in the
 global **$wp_post_types** of the main site (even after trying
 switch_to_blog( $post->blog_id );
