 Post Templates created in parent theme are not included when
 get_post_templates() is used in a child theme.

 Create a post template in a parent theme
 {{{#!php
 <?php
 /**
  * Template Name: Audio Topic
  * Template Post Type: topic
  */
 }}}

 Then in child theme functions.php, call get_post_templates()
 {{{#!php
 <?php
 add_action( 'admin_init', function() {
   $log = wp_get_theme()->get_post_templates();
   error_log( print_r( $log, true ) );
 } );
 }}}
 You will only see post templates whose .php files exist within the child
 theme root.

 FIX:
 In WP 4.8.1 wp-includes/class-wp-theme.php line 1045
 (https://github.com/WordPress/WordPress/blob/master/wp-includes/class-wp-
 theme.php#L1006)
 change:
 {{{#!php
 <?php
 $files = (array) $this->get_files( 'php', 1 );
 }}}
 to
 {{{#!php
 <?php
 $files = (array) $this->get_files( 'php', 1, true );
 }}}
