Environment: iPhone 13/14, iOS 16, Chrome, Safari Description: We use WebRTC api to stream camera to <video>. We did some business logics according to stream's width and height. But the height and width value swapped randomly. Expected result: video stream height is always larger than width on portrait mode. Actual result: video stream width height swapped randomly.
