Re: [w3c/uievents] Add specification for AltGraph key & modifier behaviour (#147)

@drwez Hi, I wrote patches for https://bugzilla.mozilla.org/show_bug.cgi?id=900750 . The summary of the new behavior is at [comment 24](https://bugzilla.mozilla.org/show_bug.cgi?id=900750#c24).

As far as I've tested with Chrome without `--enable-features=FixAltGraph`,  looks like that Chrome has already started to use `"AltGraph"` key value for `AltRight` key event when active keyboard layout has `AltGr` key. On the other hand, looks like Chrome still sets `altKey` and `ctrlKey` to true when `getModifierState("AltGraph")` returns true. I see this on an environment but I don't see such behavior on another environment. Do you do A/B test now?

Additionally, as I guessed, it's difficult to make this behavior change behind pref. So, we need to wait to land the patches until Chrome enables the new behavior in release channel. So, I'd like to know when you enable it in release channel by default.
