QtQuick controls not rendering in an MFC app

It seems that QtQuick controls are not being rendered in an MFC application. The attached Visual Studio solution uses QtWinMigrate project to integrate Qt and MFC controls.

When instantiating a QtQuick control using QtQuickWidget (a simple red Rectangle) and trying to add it to the layout of whose parent is a QWinWidget a white area is being displayed instead.

As part of the test application, I have used two native QWidget controls inside the layout where the QtQuickWidget was added : QLabel and QLineEdit and those are being rendered fine.
