By default the floating windows do not show up in the OS taskbar. Setting this property to true will cause them to be shown in the taskbar. This is particularly useful when the floating windows are allowed to be minimized but also when the floating windows are not owned windows since the window may then be behind the main window.
Note: This property only has an effect when the PaneToolWindow is hosted in a WPF Window.
