Attaching a touch event handler on ScrollView breaks the scrolling

Attaching a touch event handler like touchstart or touchend to a ScrollView makes the scroll view not scrollable.

var page = tabris.create("Page", {
  title: "Scroll Composite - Horizontal",
  topLevel: true
});

var scrollView = tabris.create("ScrollView", {
  direction: "horizontal",
  layoutData: {left: 0, top: [40, 0], right: 0, bottom: [40, 0]},
  background: "#234"
}).on("touchstart", function(event) {
  console.log("touchstart triggered: " + JSON.stringify(event));
}).appendTo(page);

for (var i = 0; i < 50; i++) {
  tabris.create("TextView", {
    layoutData: {left: i * 30 + 20, centerY: 0, width: 30},
    text: i + "°",
    foreground: "white"
  }).appendTo(scrollView);
}

page.open();

tap gesture works fine. Currently touchstart blocks scrolling on Android, but works on iOS. Possible use case would be implementing focus out for custom widgets in a scroll view.

I just retested the snippet above with the currently nightly and found that the Android client does fire the touch start event, while ios does not.
