Description

The 'touchend' event emulated by 'mouseup' should contain empty 'touches' and 'targetTouches' lists, but actually it has one touch.
For example, Chrome mode "Emulate touch events" works as expected - 'touchend' event have no any touch in 'touches' and 'targetTouches'. Mobile devices so work also.

Potential issue is in this part of the code, as I think: incubator-ripple-HEAD-24cae31\lib\client\touchEventEmulator.js

function _simulateTouchEvent(type, mouseevent) {
...
changedTouches: [touchObj],
targetTouches: [touchObj],
touches: [touchObj]
...
}

As one of the potential solutions, I suggest to check for 'touchend' event type, something like this:
...

targetTouches: type === "touchend" ? [] : [touchObj],
touches: type === "touchend" ? [] : [touchObj]

....
