QQuickWidget inside QDockWidget: move not working

[YTKOHOC]

Re: QQuickWidget inside QDockWidget: resize() not working

In qt3d's example widgets-scene3d I added following code and add quickWidget as QDockWidget:

...
    QDockWidget * dockWidget = new QDockWidget;
    dockWidget->setWidget(quickWidget);
    mainWindow.addDockWidget ( Qt::RightDockWidgetArea, dockWidget );
...

instead of adding to MDI area.
And after trying to move it (make floating, then move to another DockWidget area) app totally crashes.
I invented some crutch:

    dockWidget->setFloating(false);
    dockWidget->setFeatures(dockWidget->features() & QDockWidget::DockWidgetFeature::DockWidgetFloatable);

And after that app not crashes but I can't move the Dock Widget with 3D scene.
I may add screenshots of crashes (Windows, MinGW, MSVC 2017).

I get similar issue from Python.
It seems it works now using QQuickView instead .
Try something like this :

QQuickView * view = new QQuickView("yourfile.qml");
QWidget * quickWidget = QWidget::createWindowContainer(view);
mainWindow.addDockWidget ( Qt::RightDockWidgetArea, dockWidget );
