Re: [w3c/uievents] Add WheelEvent#wheelDelta/wheelDeltaX/wheelDeltaY (#138)

Does content depend on these attributes behaving differently in Chrome, Edge and Safari, and do they actually? If those three are well enough aligned, are there additional compat constraints that Gecko would run into if trying to add them?

As a last resort, it's possible to do something like the [navigator compatibility mode](https://html.spec.whatwg.org/multipage/webappapis.html#concept-navigator-compatibility-mode), but hopefully that shouldn't be necessary.
