Shadow does not honour Styles

Description

If I use a Shadow, and update the appropriate Style in Styles.xaml, the shadow does not apply the properties set in the style.

For example, if I change the entry in Styles.xaml to have a Red brush:

    <Style
        TargetType="Shadow">
        <Setter Property="Radius" Value="15" />
        <Setter Property="Opacity" Value="0.5" />
        <Setter Property="Brush" Value="Red" />
        <Setter Property="Offset" Value="10,10" />
    </Style>

I would expect all Shadows to be red. They remain with their default colour.

Steps to Reproduce

1. Create a new MAUI project.
2. Amend the Style in Styles.xaml, with TargetType of "Shadow", to have a Red Brush.
3. Add a Shadow to a control.
4. The Shadow is not red when the application runs and renders the Shadow.

No response

Did you find any workaround?

No. Apart from setting the Shadow's attributes locally on each ContentPage/ContentView, thus not making use of Styles.
