I made a custom renderer for LottieUWP

[assembly: ExportRenderer(typeof(LottieView), typeof(LottieViewRenderer))]

namespace Gorilla.Forms.UWP.Source.Renderer.Lottie

{

public class LottieViewRenderer : ViewRenderer<LottieView, LottieAnimationView>

{

    private LottieAnimationView AnimationView;



    protected override void OnElementChanged(ElementChangedEventArgs<LottieView> e)

    {

        base.OnElementChanged(e);



        if (Control == null)

        {

            if (e.NewElement == null) return;



            AnimationView = new LottieAnimationView()

            {

                Name = e.NewElement.AnimationPath,

                FileName = e.NewElement.AnimationPath,

                AutoPlay = true,

                RepeatCount = -1

            };



            SetNativeControl(AnimationView);

        }

    }

}

}

And here is the LottieView

public class LottieView : View

{

    public static readonly BindableProperty AnimationPathProperty = BindableProperty.Create(

        propertyName: nameof(AnimationPath),

        returnType: typeof(string),

        declaringType: typeof(LottieView));



    public string AnimationPath

    {

        get => (string)GetValue(AnimationPathProperty);

        set => SetValue(AnimationPathProperty, value);

    }

}

This works, but sometimes when hovering or waiting some seconds, I get an error:

WinRT information: Attempting to close a CanvasActiveLayer that is not top of the stack. The most recently created layer must be closed first.

This seems to be a bug inside LottieUWP or is my implementation incorrect?
