[Resolved] Can't change header status code response

[skarabeq]

After update wordpress from 4.6.1 to 4.7.2 I was unpleasantly surprised.In ajax response like this:

<?php
function post_contact_form($data)
{
    $json_return = array();
    if(!isset($data['name'])){
    $error_status_header = 422;
    status_header($error_status_header);
    $json_return['error'] =  __("Error. Please fill your name.");
    }
    else{
    $json_return['success'] = __("Form submitted.");
    }
    echo json_encode($json_return);
    wp_die();

}
add_action('wp_ajax_post_contact_form', 'post_contact_form');
add_action('wp_ajax_nopriv_post_contact_form', 'post_contact_form');

When I try to change status header to 422 , I just got http status header 200. In this case my fron-end logic was broked, because I check the ajax status code in ajax error handle. Also I tried with status code 400 the result is same. Please fix it because this bug has created extremely inconvenience to the functionality of my site.

You should be able to send arguments to wp_die(). Response code can be sent to the title argument.

​https://developer.wordpress.org/reference/functions/wp_die/
​https://developer.wordpress.org/reference/functions/_ajax_wp_die_handler/

if ( is_int( $args ) ) {
	$args = array( 'response' => $args );
} elseif ( is_int( $title ) ) {
	$args  = array( 'response' => $title );
	$title = '';
}

So if you use:

wp_die( '', 422 );

Or:

wp_die( 'Message', 'Title, array( 422 ) );

You should be able to change the response code.
