you have actually stumbled upon a bug in our implementation. Calling e.preventDefault in the touchstart handler should be enough to cancel both the tap and hold event handling.

Meanwhile, you can work around this problem by calling some internal methods of the touch structure - please take a look at the updated version of the jsbin
