Control event propagation?

[josipx]

Description

I have simple MAUI app with ContentPage containing Button with overlaying Grid control, e.g.:

 <Button VerticalOptions="Start"
            BackgroundColor="red"
            Clicked="Button_OnClicked"
            HeightRequest="100"
            Text="View 4"
            WidthRequest="100" />
<Grid BackgroundColor="#66000000" />

I would expect that Grid control overlays Button therefore events (e.g. Button click) are not triggered on underlying control. This is not the case in the latest RC3 version. I tested similar scenario in XF 5 and it works as expected (button click event is not triggered). I also tried all sorts of scenarios with InputTransparent property on controls, with no success.

Steps to Reproduce

1. Create new MAUI app
2. Add simple ContentPage with:

<Button VerticalOptions="Start" BackgroundColor="red" Clicked="Button_OnClicked" HeightRequest="100" Text="View 4" WidthRequest="100" /> <Grid BackgroundColor="#66000000" />

and click eventhandler on Page Cs code, e.g.:

private async void Button_OnClicked(object sender, EventArgs e)
{
await DisplayAlert("Message", "Button click event", "OK");
}

Because Grid overlays (hides) Button control click event should not trigger.
