LoadImageInfo does not return correct values for width and height if image is from mobile phone and image is in portrait mode

As per the title, if I want to get width/height of an image in portrait mode from a mobile phone, the width and height are incorrect (width is wider that height).

I use this code to call the method:

using (var stream = imageBlob.OpenRead())
			{
				string[] info = new[] { "source.width", "source.height", "final.width", "final.height", "result.ext", "result.mime" };

				var length = stream.Length; // set length before calling LoadImageInfo
				var result = CurrentImageBuilder.LoadImageInfo(stream, info);
				return new Tuple<int, int, long>((int)result["source.width"], (int)result["source.height"], length);
			}

Is there some setting I am missing in the call to LoadImageInfo (i.e in info)?

I've found code here on github that seems to indicate that you do actually autorotate by default for some calls (in ImageBuilder.PostDecodeStream), but I am unsure if this code is > 4.2.8 or not called when calling LoadImageInfo.

We are currently on ImageBuilder 4.2.8

Thanks

Start with LoadImageInfo and compare its behavior with the autorotation-related code in ImageBuilder.PostDecodeStream; the report says this differs for portrait images from mobile phones. Reproduce the case on ImageResizer 4.2.8 and verify that source.width and source.height report the portrait orientation correctly.
