DrawString doesn't work on maccatalyst

[BharanikhumarSR]

Description

I am using canvas DrawString method to render a text in my application. But after updating preview 13 I have faced breaking issues on setting font properties. But when I tried to set the font properties using font class, text is not visible. For android and windows, the text is rendered but the alignment is not same for the platforms.

XAML

<ContentPage.Resources>
        <ResourceDictionary>
            <local:GraphicsDrawable x:Key="GraphicsDrawable" />
        </ResourceDictionary>
</ContentPage.Resources>

 <ContentPage.Content>
      <StackLayout>
           <GraphicsView
                HeightRequest="500"
               WidthRequest="500"
               Drawable="{StaticResource GraphicsDrawable}"></GraphicsView>
     </StackLayout>
 </ContentPage.Content>

C#

public class GraphicsDrawable : IDrawable
{
    public void Draw(ICanvas canvas, RectF dirtyRect)
    {
      canvas.FontColor = Colors.Black;
      canvas.FontSize = 14;
      canvas.DrawString("Hello world", 10, 10, HorizontalAlignment.Center);
    }
}

Steps to Reproduce

• Create a new Maui Application
• Add GraphicsView to the content page.
• Create a new class and extend the class from IDrawable
• Draw a text using DrawString using ICanvas.
• Bind the drawable to the GraphicsView drawable property.

Verified on Visual Studio Enterprise 2022 main 17.2.0 Preview 2.0 [32223.438.main]. Not render text in iOS platform. Repro Project: 4993.zip iOS:

If replace "canvas.DrawString("Hello world", 10, 10, HorizontalAlignment.Center);" with "canvas.DrawString("Hello world", 10, 10, 380, 100, HorizontalAlignment.Center, VerticalAlignment.Top);", iOS and Android will work as expected.
