Items load improperly in certain cases when using dynamic creation and destruction

Load the attached QML file HangMeByClicking.qml with QMLViewer. Click repeatedly on the shown rectangle. The demo should toggle between a red and a green rectangle. The second rectangle does not get loaded properly however, and so does not toggle when clicked.

A second example has been added which makes this clearer. The red rectangle now has an animation and a binding, which works properly if the HangMeByClicking.qml is altered to start with the red rectangle, but where the binding does not work if the red rectangle is loaded second.
