In fact I have to specify: the docking / undocking directly by clicking on the dock icin does not work in the 3 previous cases. However, when initiated with the "minimize windows" button on the top right corner of the thunderbird window (ie the button with the flat line, not the square or the cross) then docking/undocking does work correctly, and the window stays on top.
