Current Behavior

Cannot set margin and padding to 0, when is set to very small value like 0.00000001 it works, but if set to 0 it goes back to default 15.

Expected Behavior

Setting margin and padding to 0 really sets it to 0.

Steps To Reproduce

Create fullscreen popup (by setting width and height to page size) and set margin and padding to 0. Example:

<toolkit:Popup xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
               xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
               xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"
               xmlns:local="clr-namespace:Mobile"
               BackgroundColor="#888"
               x:Class="Mobile.SideMenu"
               Padding="0.00000001"
               Margin="0.00000001">

</toolkit:Popup>

    partial class SideMenu : Popup
    {
        public SideMenu()
        {
            InitializeComponent();

            Application.Current!.Windows[0].Page!.SizeChanged += AdjustSize;

            Layout.GestureRecognizers.Add(new TapGestureRecognizer { Command = new Command(() => { CloseAsync(); }) });

            AdjustSize(this, new EventArgs());
        }

        private void AdjustSize(object? sender, EventArgs e)
        {
            WidthRequest = Application.Current!.Windows[0].Page!.Width;
            HeightRequest = Application.Current!.Windows[0].Page!.Height;
        }
    }
