      Description

      When using MultiPointTouchArea inside a delegate of a ListView it does not process touch events nearly as well as mouse events when the list becomes flickable.

      Expected: Touch events should be handled as reliably well as mouse events are for a MultiPointTouchArea inside a flickable ListView

      Attachments:
      flickable-touch.qml: Sample QML file that can be run with qmlscene to observe the issue. Try toggling each delegate when the list is flickable.
