Custom action button in the list of admin orders on Woocommerce 3.3+

Question

Since the version of WooCommerce version 3.3+ below, which displays a custom action button in the list of admin orders, no longer works.

// Add your custom order action button
add_action( 'woocommerce_admin_order_actions_end', 'add_custom_order_actions_button', 100, 1 );
function add_custom_order_actions_button( $order ) {

    // Get the tracking number
    $traking_number = get_post_meta( $order->get_id(), '_aftership_tracking_number', true );
    if( empty($traking_number) ) return;

    // Prepare the button data
    $url    = esc_url('https://track.aftership.com/'.$traking_number.'?');
    $name   = esc_attr( __('Tracking', 'woocommerce' ) );
    $action = esc_attr( 'view tracking' ); // keep "view" class for a clean button CSS

    // Set the action button
    printf( '<a class="button tips %s" href="%s" data-tip="%s" target="_blank">%s</a>', $action, $url, $name, $name );
}

// The icon of your action button (CSS)
add_action( 'admin_head', 'add_custom_order_actions_button_css' );
function add_custom_order_actions_button_css() {
    echo '<style>.view.tracking::after { font-family: woocommerce; content: "\e005" !important; }</style>';
}

The code is derived from this answer: Add a custom URL link to the admin order list page in WooCommerce

What have they changed to prevent it from working in the new version?
How can I make it work in Woocommerce version 3.3+?
