      Description

      QQuickWindow::sceneGraphInitialized and QQuickWindow::sceneGraphInvalidated signals won't be emitted when set QT_QUICK_BACKEND=openvg.

       

      However, if add emits in qtdeclarative/src/plugins/scenegraph/openvg/qsgopenvgcontext.cpp as followings, it works. Is this bug or there is other reason? (QSGD3D12RenderContext::initialize() and QSGD3D12RenderContext::invalidate() emit both signals)
