In Chromium, when the invalid '?' are removed then you get the following,
```javascript
> new DeviceMotionEvent('', {acceleration: {}}).acceleration
DeviceAcceleration {x: null, y: null, z: null}
> new DeviceMotionEvent('', {acceleration: null}).acceleration
DeviceAcceleration {x: null, y: null, z: null}
> new DeviceMotionEvent('', {acceleration: undefined}).acceleration
null
> new DeviceMotionEvent('', {}).acceleration
null
```
Based on my understanding from the discussion above this is correct according to the WebIDL specification.
The change from the non-compliant behavior is in this case,
```javascript
> new DeviceMotionEvent('', {acceleration: null}).acceleration
null
```
