Hi Team, While comparing HTML Spec with IDL files in WebKit, I noticed that following is not in web specification: Web Spec: https://w3c.github.io/deviceorientation/#device-motion-event-api WebKit Source: https://searchfox.org/wubkat/rev/e6b945d8d215583ba34dffcc8f93a0c1c2662c0b/Source/WebCore/dom/DeviceMotionEvent.idl ___ Note - Blink does not have this but Gecko does. Also Blink removed it in following (2017): https://chromium.googlesource.com/chromium/src.git/+/0921e8319f228e406019b434701ac9f181ee8ea1 They also removed `DeviceOrientationEvent.initDeviceOrientationEvent` for which I will create separate bug to make it easier to revert if needed and manage stuff. CCing @Anne - for his input. Thanks!
