Style is not replaced

[HausBJB]

Description

I'm trying to change a style via binding, unfortunately it only works once.

The first style sets a RadialGradientBrush, the second style reverses this and it doesn't work.

The button keeps the style even if I set the stzle to null

Steps to Reproduce

1.Create Maui App 1.Create 2 Styles

Style 1

                var onStyle = new Style(typeof(Border));
                //ON Style
                var gradienStopsON = new GradientStopCollection()
                {
                    new GradientStop(Color.FromArgb("#f8f8f8"),0.3f),
                    new GradientStop(Color.FromArgb("#f5f7f8"),0.5f),
                    new GradientStop(Color.FromArgb("#e8eef7"),0.8f),
                    new GradientStop(Color.FromArgb("#dee9f6"),1.0f)
                };
                var radialGradient = new RadialGradientBrush(gradienStopsON);
                radialGradient.Center = new Point(0.48f, 0.58f);
                onStyle.Setters.Add(new Setter
                {
                    Property = Border.BackgroundProperty,
                    Value = radialGradient
                });

                return onStyle;

Style 2

var offStyle = new Style(typeof(Border));

                //Off Style
                var shadow = new Shadow();
                shadow.Brush = new SolidColorBrush(Color.FromArgb("#0473f1"));
                shadow.Opacity = 0.20f;
                shadow.Radius = 18;
                shadow.Offset = new Point(0, 4);
                offStyle.Setters.Add(new Setter
                {
                    Property = Border.ShadowProperty,
                    Value = shadow
                });
                offStyle.Setters.Add(new Setter
                {
                    Property = Border.BackgroundProperty,
                    Value = new SolidColorBrush(Colors.White)
                });

                return offStyle;

3. Create a Border

<Border
                                                    BackgroundColor="White"
                                                    HeightRequest="40"
                                                    Stroke="White"
                                                    StrokeThickness="0"
                                                    Style="{Binding Style}"
                                                    WidthRequest="40">
                                                    <Image
                                                        Aspect="Center"
                                                        HorizontalOptions="Center"
                                                        Source="{Binding IconName}"
                                                        VerticalOptions="Center" />
                                                    <Border.StrokeShape>
                                                        <EllipseGeometry
                                                            Center="20,20"
                                                            RadiusX="20"
                                                            RadiusY="20" />
                                                    </Border.StrokeShape>
                                                </Border>

4. Change Style

        [ObservableProperty]
        public Style style;

        Style = onStyle;

iOS

As you can see here the RadialGradientBrush is applied but you can't go back
