Setting InputTransparent=true on a layout will remove the background
Description
I would expect this to appear as a Green box with a button, instead it is a red box with a button - the green background is gone.
<Grid x:Name="rootLayout" InputTransparent="False" Background="Red">
<Grid x:Name="nestedLayout" InputTransparent="True" Background="Green">
<Button x:Name="testButton" Text="Test Button" Clicked="ClickSuccess" HorizontalOptions="Center" VerticalOptions="Center" InputTransparent="False" />
</Grid>
</Grid>
To get the background that is input transparent, we add a canvas to the layout - except that we can remove this at any time. The LayoutHandler for Windows just adds and removes children based on index, yet the background is at index 0.
Steps to Reproduce
- File | New | Maui App
- Copy the XAML
- Run
- Observe the red background

Right now, the Layout is handing this case of a background, but probably for layouts we should use a wrapper view and put the background in there instead. This makes the layout handler code far simpler. The wrapper view can be the part that adds a canvas and manages that.
