For now, the pointer event hasn't turned on for mobile yet, but we should think how to do anti-fingerprinting for pointer events on mobile. The current fingerprinting protection for pointer event is to spoof every pointer event into mouse pointer event. But for mobile, it could be not a good idea to use this approach considering the environment of mobile is extremely different. We should use a different type, like "touch", for mobile. Masayuki suggests that maybe we can use a pref to adjust the type we are spoofing. Like, using a pref in all.js which is 'mouse' and override it in mobile.js. And we should consider other fields, like width, height, pressure and so on.
