Custom billing field order

I am having a similar issue where I change the order of woocommerce_shipping_fields and woocommerce_billing_fields but they are re-ordered back with javascript. If I disable JS on my account page the fields are ordered properly.

As mikejolley stated here: https://github.com/woocommerce/woocommerce/issues/14618 this should be answered here but I cannot find it. Any help is appreciated!

add_filter( ‘woocommerce_checkout_fields’ , ‘custom_override_checkout_fields’ );
function custom_override_checkout_fields( $fields ) {
$fields[‘billing’][‘landline_phone’] = array(
‘label’ => __(‘Landline phone’, ‘woocommerce’),
‘placeholder’ => _x(”, ‘placeholder’, ‘woocommerce’),
‘required’ => false,
‘clear’ => false,
‘type’ => ‘tel’,
‘priority’ => ‘105’,
);
return $fields;
}

// Display under the admin section
add_action( ‘woocommerce_admin_order_data_after_billing_address’, ‘my_custom_checkout_field_display_admin_order_meta’, 10, 1 );
function my_custom_checkout_field_display_admin_order_meta($order){
echo ‘<p>‘.__(‘Landline Phone’).’: ‘ . get_post_meta( $order->id, ‘_landline_phone’, true ) . ‘</p>’;
}

//Save fields after checkout
add_action( ‘woocommerce_checkout_update_order_meta’, ‘my_custom_checkout_field_update_order_meta’ );
function my_custom_checkout_field_update_order_meta( $order_id ) {
if ( ! empty( $_POST[‘landline_phone’] ) ) {
update_post_meta( $order_id, ‘_landline_phone’, sanitize_text_field( $_POST[‘landline_phone’] ) );
}
}
