.NET MAUI `Button.OnClicked` Event Does Not Fire When Clicked / Tapped

After adding a Clicked event handler in the code behind, and adding it to my Button in XAML, the HandleClicked event handler never fires when tapping the button.

What have I done wrong to cause the Button.Clicked event not to fire?

MainPage.xaml

<Button x:Name="AddButton"
  Clicked="HandleClicked"
  Text="Add"
  HorizontalOptions="Start"
  VerticalOptions="End"
  WidthRequest="100">
  <Button.GestureRecognizers>
    <PointerGestureRecognizer PointerEntered="PointerGestureRecognizer_PointerEntered" />
  </Button.GestureRecognizers>
</Button>

MainPage.xaml.cs

async void HandleClicked(object? sender, EventArgs e)
{
  var toast = CommunityToolkit.Maui.Alerts.Toast.Make("Add has been clicked");
  await toast.Show();
}

Steps To Reproduce

1. Run the project on an Android device/emulator
2. Expand the expander at the bottom
3. Try to click on either button
4. No toast is fired

The issue is that you've aded a GestureRecognizer to your Button which is overriding the Clicked action.

When you remove the GestureRecognizer, the Clicked event fires:

  <Button x:Name="AddButton"
          Clicked="AddClicked"
          Text="Add"
          HorizontalOptions="Start"
          VerticalOptions="End"
          WidthRequest="100">
  </Button>

I do not know if this behavior is intended by the .NET MAUI engineering team. I recommend opening this Issue on the .NET MAUI GitHub Repo.
