It cannot be looped after enlarging the window.

I have developed a code that initiates the Timeline in the Reality Composer Pro scene every 12.93 seconds.

RealityView { … }
    .onAppear {
        startTimer()
    }
    .onDisappear {
        stopTimer()
    }
    func startTimer() {
        timer = Timer.scheduledTimer(withTimeInterval: 12.93, repeats: true) { _ in
            action()
        }
    }
    
    func stopTimer() {
        timer?.invalidate()
    }
    func action() {
        print(“SunUpDown”)
        NotificationCenter.default.post(
            name: NSNotification.Name(“RealityKit.NotificationTrigger”),
            object: nil,
            userInfo: [
                “RealityKit.NotificationTrigger.Scene”: scene as Any,
                “RealityKit.NotificationTrigger.Identifier”: “SunUpDown”
            ]
        )
    }

Upon receiving the “SunUpDown” command, Timeline will be executed.

However, everything was functioning normally when I was running the scene, and I could continue looping until I attempted to zoom in on the window and discovered that it ceased looping. Could you please provide an explanation for this behavior?

Note: The window type is volumetric, and the parameter of the defaultWorldScaling modifier is dynamic.
