The spec needs to change here, a nullable dictionary doesn't make sense. As a
drive-by, can you also update the link above to
https://w3c.github.io/mediacapture-image/#ImageCaptureAPI?

Actually, leave the spec link for another CL when you actually touch the file.
(Mass-replacement of /TR/ links also welcome.)

I will reverse the change because the change will not compile. 

     [CallWith=ScriptState, RaisesException] Promise<Blob> takePhoto();
     [CallWith=ScriptState, RaisesException] Promise<ImageBitmap> grabFrame();
 };
