We're using iscroll-probe with the probeType set to 3 meaning that a scroll event is fired whenever the slider is moved.
However, activating the handy keybindings option and moving the slider via keyboard doesn't emit any events whatsoever.

What's happening is: scrollTo is called with time = 0. That's why the if-condition is true leading to _translate being executed instead of _animate. _animate would emit events. _translate doesn't.
