Comment 9 for bug 1313727

One other thing - I'm not sure whether it would be worthwhile reimplementing content::NativeWebKeyboardEvent by omitting native_web_keyboard_event_aura.cc from the build and providing our own. It's not a lot of code, and it has a pointer (os_event) on which to store the original event. That might save some effort recreating it here.

You don't have to do that though :)
