Qml binding error in ScrollViewHelper.qml

When running examples which use a scroll view (for instance the mapviewer example from the Qt Location plugin) then the following error is shown in the application output:

<code>
file:///E:/qt/qt56dev/built/qml/QtQuick/Controls/Private/ScrollViewHelper.qml:192:9: QML Binding: Property 'raised' does not exist on Item.
file:///E:/qt/qt56dev/built/qml/QtQuick/Controls/Private/ScrollViewHelper.qml:145:9: QML Binding: Property 'raised' does not exist on Item.
</code>

The problem seems to occur only on Windows.
Steps to reproduce:
1.) Start the mapviewer example (Qt Location plugin).
2.) Scroll and zoom around.
3.) Press the top menu bar -> now the error message is printed to the debug output.
