title: Cursor shape changed even over an overlapping rectangle in QML
body: <p>With the following code, the green rectangle entirely overlaps the red rectangle, but when the mouse is over the (hidden) red rectangle, my cursor shape is still changed according to the red MouseArea cursorShape.
  Any idea to prevent this behavior?</p>
  
  <pre><code>import QtQuick 2.0
  
  Rectangle {
      width: 360
      height: 360
  
      Rectangle {
          color: "red"
          anchors.top: parent.top
          anchors.bottom: parent.bottom
          width: 100
          MouseArea {
              anchors.fill: parent
              hoverEnabled: true
              cursorShape: "ClosedHandCursor"
          }
      }
  
      Rectangle {
          color: "green"
          anchors.fill: parent
          MouseArea {
              anchors.fill: parent
              hoverEnabled: true
          }
      }
  }
  </code></pre>
