Cannot set DragUI visual.

### Describe the bug

When I set the visual for a drag and drop operation using...

`args.DragUI.SetContentFromBitmapImage(bmp);`

The image is not visible.

### Steps to reproduce the bug

1. Create a handler for DragStarting
2. Provide a BitmapImage as a source image
3. Set the visual.

### Expected behavior

I expect to see the image.

### Screenshots


### NuGet package version

WinUI 3 - Windows App SDK 1.6.1: 1.6.240923002

### Windows version

Windows 11 (22H2): Build 22621

### Additional context

[DragUI.SetContentFromSoftwareBitmap() does not show the bitmap #4528](https://github.com/microsoft/microsoft-ui-xaml/issues/4528)

[DataGridRow Drag and Drop Visual does not display most of the time #4545](https://github.com/microsoft/microsoft-ui-xaml/issues/4545)

Start by reproducing the issue with a DragStarting handler and args.DragUI.SetContentFromBitmapImage(bmp) on Windows App SDK 1.6.1. Read the linked issues #4528 and #4545 for related behavior; done means the supplied BitmapImage is visible as the drag visual.
