      Description

      To reproduce:

      import QtQuick 2.0
      import QtQuick.Window 2.2
      
      Window {
          id: win
          visible: true
          width: 800
          height: 600
      
          Component {
              id: cmp
              Rectangle {
                  color:"red"
                  height: win.height
              }
          }
          Component.onCompleted: {
              cmp.incubateObject(contentItem, {width: Qt.binding(function(){ return win.width })})
          }
      }
