CascadeInputTransparent="False" is not working on ContentView

[pauldendulk]

Description

If a ContentView has InputTransparent set to true and CascadeInputTransparent set to false the child controls do not receive input.

Steps to Reproduce

1. Create a new Maui app in Visual Studio with the button click sample code.
2. Replace the content of MainPage.xml with:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="CascadeInputTransparent.MainPage">

    <ContentView
        InputTransparent="True"
        CascadeInputTransparent="False">    
        <Button
            x:Name="CounterBtn"
            Text="Click me"
            SemanticProperties.Hint="Counts the number of times you click"
            Clicked="OnCounterClicked"
            HorizontalOptions="Center" />
    </ContentView>
</ContentPage>

3. Click the button and nothing happens.

Did you find any workaround?

Not one that solves my problem.

Note, this problem also exists in the ScrollView. It does not exist in the VerticalStackLayout. I did not test anything else.

This is an interesting one because CascadeInputTransparent is really only on Layouts, but now ContentView is also a Layout... @hartez not sure if this was a conscious decision to always make ContentView cascade (and the property is not supposed to be there) or is this a bug?
