I am using below code for wp_kses(). But it's ignoring rel & target in the result. I want to show rel="nofolow" target="_blank" in my result (link).

$link = "Here is my link: <a href="my-link" rel="nofollow" target="_blank">Link Text</a>" 

$allowed_tags= array(
                        'br' => array(),
                        'p' => array(),
                        'a'  => array(
                                'href'     => true,
                                'rel'      => true,
                                'target'   => true,                             
                            ),
                );


$result = wp_kses( $link, $allowed_tags );

Output result: Here is my link: <a href="my-link">Link Text</a>

Expected result: Here is my link: <a href="my-link" rel="nofollow" target="_blank">Link Text</a>
