Missing 403 status header for ‘not allowed’ question page

includes/common-pages.php:127 sets 403 status header if user has no permission to view private question, which is good. But afterwards the hook ‘ap_template_include’ fires and function ‘template_include_theme_compat’ from includes/class-theme.php is called, which calls ‘ap_theme_compat_reset_post’ from includes/theme.php, where status header is set back to 200 at line 1156.
I believe that check in previous line ! $wp_query->is_404() should be changed, because there’s at least 403 status possible too.
Whould you mind to fix this in next release?
