[BUG] Grid is always InputTransparent (.NET MAUI 9.0 Preview 2)

[janne-hmp]

Description

It seems that all grids are InputTransparent even when InputTransparent is set to false.

Steps to Reproduce

1. Create an default .NET MAUI project
2. Add a Grid on the top of the existing default XAML (by making a root grid and putting the new Grid and ScrollView into it). Set the Grid's InputTransparent to false (and Horizontal and Vertical Options to FillAndExpand so it covers the Button for sure)

XAML is then:

<?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="Net9MauiTest.MainPage">

    <Grid HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
        <ScrollView>
            <VerticalStackLayout
                Padding="30,0"
                Spacing="25">
                <Image
                    Source="dotnet_bot.png"
                    HeightRequest="185"
                    Aspect="AspectFit"
                    SemanticProperties.Description="dot net bot in a race car number eight" />

                <Label
                    Text="Hello, World!"
                    Style="{StaticResource Headline}"
                    SemanticProperties.HeadingLevel="Level1" />

                <Label
                    Text="Welcome to &#10;.NET Multi-platform App UI"
                    Style="{StaticResource SubHeadline}"
                    SemanticProperties.HeadingLevel="Level2"
                    SemanticProperties.Description="Welcome to dot net Multi platform App U I" />

                <Button
                    x:Name="CounterBtn"
                    Text="Click me" 
                    SemanticProperties.Hint="Counts the number of times you click"
                    Clicked="OnCounterClicked"
                    HorizontalOptions="Fill" />
            </VerticalStackLayout>
        </ScrollView>
        <Grid HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" InputTransparent="False" />
    </Grid>
</ContentPage>

4. Build the project
5. You can still press the button

Version with bug

9.0.0-preview.1.9973

Is this a regression from previous behavior?

Yes, this used to work in Xamarin.Forms

Last version that worked well

Unknown/Other

Affected platforms

Android

Affected platform versions

Android 14, perhaps all others as well, did not test

Did you find any workaround?

Yes, I added an empty TapGestureRecognizer to the Grid, but the point is that InputTransparent does not work for the Grid. If it is intended, InputTransparent should be marked deprecated for Grid.

Hi @janne-hmp. We have added the "s/try-latest-version" label to this issue, which indicates that we'd like you to try and reproduce this issue on the latest available public version. This can happen because we think that this issue was fixed in a version that has just been released, or the information provided by you indicates that you might be working with an older version.

You can install the latest version by installing the latest Visual Studio (Preview) with the .NET MAUI workload installed. If the issue still persists, please let us know with any additional details and ideally a reproduction project provided through a GitHub repository.

This issue will be closed automatically in 7 days if we do not hear back from you by then - please feel free to re-open it if you come back to this issue after that time.

There was a workaround found in #9153 (comment)

Simplest workaround for me was adding an empty TapGestureRecognizer to the view that's over top.
