Tint size not correct in Xamarin Forms with .NETStandard 2.0

I created a new xamarin forms project with .NET Standard 2.0 and in the sample i changed the label to Button and added the background color. While the button is clicked the ripple animation is shown small and concentrated to the top left corner and not the entire button width and height

    <Button Text="Welcome to Xamarin.Forms!" HorizontalOptions="Center" 
       VerticalOptions="CenterAndExpand" BackgroundColor="Lime"  />

Is there anything we need to do to make the ripple animation correct.

Please see the image attached.!
