UIStatusBarAnimation style .slide not working in iOS 15

Question

Following with the UIViewController worked until iOS 15. Status bar animated with the 'slide' method. Now it just fades away.

self.setNeedsStatusBarAppearanceUpdate()


override final var prefersStatusBarHidden : Bool {
    return false
}

override var preferredStatusBarUpdateAnimation: UIStatusBarAnimation {
    return .slide
}

Is this a bug?
