I discussed the case with my colleagues and it seems the problem is caused by the events in this browser. The QTWebkit supports touch and mouse events, while the Kendo UI will use the touch events if available. I am afraid currently I can not suggest a suitable workaround for your scenario, but the needed functionality is under consideration from our developer team.
