I’m encountering an issue with a DrawingImage not being visible in the designer or during run-time within a WPF application. Here’s the setup:

MainWindow.xaml

    <Window.Resources>
        <ResourceDictionary Source="TestDictionary.xaml"/>
    </Window.Resources>
    
    <Button>
        <Image Source="{StaticResource close_FILL0_wght400DrawingImage}"/>
    </Button>

TestDictionary.xaml

    <DrawingImage x:Key="close_FILL0_wght400DrawingImage">
        <DrawingImage.Drawing>
            <DrawingGroup ClipGeometry="M0,-960 V0 H960 V0 H-960 Z">
                <DrawingGroup.Transform>
                    <TranslateTransform X="0" Y="960" />
                </DrawingGroup.Transform>
                <GeometryDrawing Brush="#FF000000" Geometry="F1 M960,960z M0,0z M256,-200L200,-256 424,-480 200,-704 256,-760 480,-536 704,-760 760,-704 536,-480 760,-256 704,-200 480,-424 256,-200z" />
            </DrawingGroup>
        </DrawingImage.Drawing>
    </DrawingImage>

Despite setting the Source of the Image to {StaticResource close_FILL0_wght400DrawingImage}, the DrawingImage is not visible as expected.

Any insights or suggestions on what might be causing this visibility issue would be greatly appreciated. Thank you!
