Windows: floating QDockWidget not repositioned on screen layout change

Unlike QMainWindow and QDialog, a floating QDockWidget does not get repositioned when the screen layout (number of screens) is changed so that the DockWindow is not visible anymore.

Typical use cases are removing a laptop from its docking station (with multi-screen setup) or remote connecting to a computer that has multiple screens. In theses scenarios it is impossible to reach the floating DockWindow that was positioned on a screen which is now not visible anymore.
