Issue with action button in WooCommerce admin order list for custom order status

Question

I have created custom order status "Ready to dispatch" and custom action button as well.

The problem and question is: when I have clicked on the custom action button, order status has changed, but default action button "Complete" disappeared.

How can I make that after click of custom action button, "Complete" action button retain?

Any advice would be appreciated

My current code:

// Register new status
function register_awaiting_shipment_order_status() {
    register_post_status( 'wc-ready-to-dispatch', array(
        'label'                     => 'Ready to dispatch',
        'public'                    => true,
        'exclude_from_search'       => false,
        'show_in_admin_all_list'    => true,
        'show_in_admin_status_list' => true,
        'label_count'               => _n_noop( 'Ready to dispatch (%s)', 'Ready to dispatch (%s)' )
    ) );
}
add_action( 'init', 'register_awaiting_shipment_order_status' );

// Add your custom order status action button (for orders with "processing" status)
add_filter( 'woocommerce_admin_order_actions', 'add_custom_order_status_actions_button', 100, 2 );
function add_custom_order_status_actions_button( $actions, $order ) {
    // Display the button for all orders that have a 'processing' status
    if ( $order->has_status( array( 'processing' ) ) ) {

        $action_slug = 'ready-to-dispatch';

        // Get Order ID (compatibility all WC versions)
        $order_id = method_exists( $order, 'get_id' ) ? $order->get_id() : $order->id;
        // Set the action button
        $actions['ready-to-dispatch'] = array(
            'url'       => wp_nonce_url( admin_url( 'admin-ajax.php?action=woocommerce_mark_order_status&status=ready-to-dispatch&order_id=' . $order_id ), 'woocommerce-mark-order-status' ),
            'name'      => __( 'Ready to dispatch', 'woocommerce' ),
            'action'    => 'ready-to-dispatch', // keep "view" class for a clean button CSS
        );
    }
    return $actions;
}

// Set Here the WooCommerce icon for your action button
add_action( 'admin_head', 'add_custom_order_status_actions_button_css' );
function add_custom_order_status_actions_button_css() {
    $action_slug = 'ready-to-dispatch';
    echo '<style>.wc-action-button-'.$action_slug.'::after { font-family: woocommerce !important; content: "\f344" !important; }</style>';
}

// Adding custom status 'awaiting-delivery' to order edit pages dropdown
add_filter( 'wc_order_statuses', 'custom_wc_order_statuses' );
function custom_wc_order_statuses( $order_statuses ) {
  $new_order_statuses = array();

   // add new order status after processing
   foreach ( $order_statuses as $key => $status ) {

       $new_order_statuses[ $key ] = $status;

       if ( 'wc-processing' === $key ) {
           $new_order_statuses['wc-ready-to-dispatch'] = 'Ready to dispatch';
       }
   }

   return $new_order_statuses;
}


// Adding custom status 'awaiting-delivery' to admin order list bulk dropdown
add_filter( 'bulk_actions-edit-shop_order', 'custom_dropdown_bulk_actions_shop_order', 1, 1 );
function custom_dropdown_bulk_actions_shop_order( $actions ) {
    $actions['mark_ready-to-dispatch'] = __( 'Ready to dispatch', 'woocommerce' );
    return $actions;
