Click the small icon with multiple windows at the top left of any visible panel. This "pops out" the panel to make it a floating window.
If you immediately double click the title bar of the popped out window, it will be docked again. Fine.
However, if you close the panel window (because double-clicking on the title bar is not at all an obvious way to re-dock a window, at least on OSX) and then re-open the panel, double-clicking the panel window now zooms it to full screen rather than re-docking the window.
As far as I can see there is no way to get the floating window back into its docked position within the main window thereafter.
