Touch event timeout on mobile sites

Chrome on Android currently has a touch ACK timeout of 200ms for desktop sites. If the renderer does not respond to a touch event before the timeout delay, the touch sequence is cancelled and any associated gestures are dispatched. This change restores a touch timeout for sites with a mobile-friendly viewport, but with a timeout delay of 1 second.

Comments

The touch timeout is but an intermediate solution as we work to provide a more functional and rational experience for unresponsive content. See crbug.com/504904.
