Created attachment 477393 [details] Basic web pages to test iframe and motion/orientation events. I think the regression has been discussed already in https://bugs.webkit.org/show_bug.cgi?id=301294 but the title of that report is a bit misleading. Motion and orientation events are never dispatched in iframes even after granting permission behind user gesture from within the iframed page. The parent page is configured with `allow="accelerometer; gyroscope; magnetometer;"`. It only works if the parent page and the iframed page are hosted on the same domain.
