    Description

      ScrollView bounce is broken when using Macbook's Touchpad or Apple Magic Mouse on Mac OS X. It either scrolls too far away and sticks in that position, or the scrolling wraps around and continues from the bottom. ScrollView is almost unusable, please see the attached video.

      Caused by this commit:
      cd qtdeclaractive/
      git revert a6ed830f4779e218b8e8f8d82dc4aa9b4b4528a1

      import QtQuick 2.3
import QtQuick.Controls 1.2
import QtQuick.Window 2.0
import QtQuick.Dialogs 1.2

ApplicationWindow {
	title: qsTr("Hello World")
	width: 640
	height: 480

	ScrollView {
