By default, the floating windows are owned windows. As such the floating windows will always stay above the owner window and will be hidden when the owning window is minimized. Setting this property to false indicates the floating window should not be owned. Therefore it may go behind the main window with regards to z-order.
Note: This property only has an effect when the PaneToolWindow is hosted in a WPF Window.
