Shadow not displaying properly in Border

[jknaudt21]

Description

I'm trying to add a <Shadow> to a border and there are a couple of issues that I'm encountering.

1. If the border is transparent (i.e doesn't BorderBackground set) the border will not display a shadow in Windows or will display a grey rectangle on Android

2. If the border has variable height and width using Minimum/Maximum width requests, the border will render completely off in Windows and will not move if the window is resized. Moreover, if I were to resize my screen, the shadow will sometimes update but it will not move with the border I'm manipulating. On Android the shadow will just display in the same fashion as in point 1

Steps to Reproduce

1. Create a new Maui Project
2. Add these lines:

    <ScrollView>
        <Border Stroke="Green"
                    StrokeThickness="1"
                    BackgroundColor="White"
                    MaximumHeightRequest="400"
                    MaximumWidthRequest="500"
                    MinimumHeightRequest="300"
                    MinimumWidthRequest="400">
                <Border.Shadow>
                    <Shadow Brush="Black"
                        Radius="40"
                        Opacity="0.8"/>
                </Border.Shadow>
        </Border>
    </ScrollView>

3. Build and run the project
4. Remove the BackgroundColor property in Windows and the border will disappear

Did you find any workaround?

One can add a determined HeightRequest and WidthRequest to the border to minimize the errors in Windows. I haven't found a workaround in Android.
