Multi touch on Chrome and Surface pro 2?

I’m trying to create a web build on Chrome on Surface pro 2 (Windows 8)

However when every I try to use a two finger swipe on it Chrome will Scroll Up and down and Unity Web Player will ignore it.

Do anyone know how to get the two finger swipe to work?

Take a look at this link: Input.touches

Maybe will help you.
Obs: I don’t know if webplayer builds can handle multitouch events
