Center stage control mode not working for iPad on front camera with .photo session preset.

I am working on an iPad app using the front camera. The camera logic is implemented using the AVFoundation framework. During a session I use central stage mode to center the face with front camera . Central stage mode works fine in all cases except when I set the session preset photo. In other presets: high, medium, low, cif352x288, vga640x480, hd1280x720, hd1920x1080, iFrame960x540, iFrame1280x720, inputPriority presets central stage mode working except photo session preset. Can you explain why this happens or maybe it is an unobvious bug?

Code snippet:

final class CameraManager {
    
    //MARK: - Properties
    private let captureSession: AVCaptureSession
    private let photoOutput: AVCapturePhotoOutput
    private let previewLayer: AVCaptureVideoPreviewLayer
    
    //MARK: - Init
    init() {
        captureSession = AVCaptureSession()
        photoOutput = AVCapturePhotoOutput()
        previewLayer = AVCaptureVideoPreviewLayer(session: captureSession)
    }
    
    //MARK: - Methods Setup Camera and preview layer
    func setupPreviewLayerFrame(view: UIView) {
        previewLayer.frame = view.frame
        view.layer.insertSublayer(previewLayer, at: 0)
        setupCamera() 
    }
    
    private func setupCamera() {
        guard let videoCaptureDevice = AVCaptureDevice.default(.builtInWideAngleCamera, for: .video, position: .front) else { return }
        AVCaptureDevice.centerStageControlMode = .app
        AVCaptureDevice.isCenterStageEnabled = true
        
        do {
            let input = try AVCaptureDeviceInput(device: videoCaptureDevice)
            captureSession.addInput(input)
            captureSession.addOutput(photoOutput)
            
            /// high,  medium, low, cif352x288, vga640x480, hd1280x720, hd1920x1080, iFrame960x540, iFrame1280x720 and inputPriority presets  working  except photo session preset
            captureSession.sessionPreset = .photo
            
            DispatchQueue.global(qos: .userInteractive).async {
                self.captureSession.startRunning()
            }
            
        } catch {
            print("Error setting up camera: \(error.localizedDescription)")
        }
    }
}
