Hi @hakimelek ! @querymetrics has fixed this issue, and will be backporting it soon.

Thanks for mentioning the prefixed screen.msOrientation and screen.mozOrientation, I hadn't included those in my fix but it would help to support more browsers.

iOS doesn't support the Screen Orientation API, but it does support the deprecated window.orientation which will give us the orientation (see https://developer.mozilla.org/en-US/docs/Web/API/Window/orientation).
