Re: [deviceorientation] Invalid IDL in DeviceMotionEventInit

Yes, I mean "nullable."

Yes, Chromium allows the invalid IDL. For reference for the current behavior I recommend looking at [device_orientation/motion/optional-event-properties.html](https://chromium.googlesource.com/chromium/src/+/e2e7cd911060f081cec552e230701a2366b12d0d/third_party/WebKit/LayoutTests/device_orientation/motion/optional-event-properties.html).

There are no bugs that I can find currently filed for this mismatch with the WebIDL specification but I might be missing context here because I am not on the team responsible for the WebIDL bindings generator.
