I don NOT want a ToolWindow float. I have disabled the ContextMenuService and the DragDropService. But end-user still can double click the title bar to make the ToolWindow floating. (Double-clicking the title bar of a ToolWindow un-docks the panel so that it floats. Double-clicking the title bar of a floating window docks the ToolWindow.)
How to disable the double-click event to prevent the ToolWindow floating?
