System.Drawing.Bitmap.FromStream fails when called with ZipWrappingStream

I'm currently extracting images from a Word document. However, Bitmap's `FromStream` function is failing with a "Parameter Not Valid" exception when called with the stream from OpenXML's ImagePart (ZipWrappedStream).

```C#
// ... code the locates the correct blip node

// get the r:embed value (first attribute)
var blipId = imgNode.Attributes[0].Value;

// get the open xml image part
ImagePart img = (ImagePart)wordDoc.MainDocumentPart.GetPartById(blipId);

// get a stream containing the wmf data
// stream is type System.IO.Packaging.ZipWrappingStream
var streamFromOpenXML = img.GetStream();

// this fails with Argument Exception, Parameter Not Valid
var imgToSave = Bitmap.FromStream(streamFromOpenXML);

// however, this works as expected
var mstream = new MemoryStream();
streamFromOpenXML.CopyTo(mstream);
mstream.Seek(0, SeekOrigin.Begin);
var imgToSave = Bitmap.FromStream(mstream);
```

This is using .NET Core 3.1, using the System.Drawing.Common (v 4.7.0) package from NuGet.
