std value for radio not considered on clone

Please consider the following field:

array (
    'id' => $prefix . 'radio_w1rh3xgybz',
    'name' => esc_html__( 'Business address source', 'text-domain' ),
    'type' => 'radio',
    'std' => 'organisation_this',
    'options' => array(
        'organisation_this' => esc_html__( 'This organisation', 'text-domain' ),
        'organisation_other' => esc_html__( 'Other organisation', 'text-domain' ),
        'home' => esc_html__( 'Home address', 'text-domain' ),
    ),
    'inline' => 1,
    'required' => 1,
    'visible' => array(
        'when' => array(
            array (
                0 => 'contact_post_4jdje2047jy',
                1 => '!=',
                2 => '',
            ),
        ),
        'relation' => 'and',
    ),
),

That field is located within a group that can be cloned. std is only taken into account for the first dataset, not for clones. I'm on WordPress 5.3.3 with current Meta Box downloaded today.
