ImageButton Orientation not working (Labs)

The following places the image to the left of the text on IOS:

        var button = new ImageButton() {
            ImageHeightRequest = 50,
            ImageWidthRequest = 50,
            Orientation = ImageOrientation.ImageOnTop,
            Image = "Images/iconbeast/bell",
            Text = "Click Me",
        };

I've tried all the workarounds and then pulled them all out. Is there something I'm missing. This is a PCL Based shared Forms library. All references/packages in both projects are up to date.
