Impossible to re-dock the preview pane once undocked

[toobaz]

I did the mistake of clicking the "undock" button just above the preview window.

Now it floats as an independent window, and I couldn't find any way to bring it back to the default. I tried dragging, checking all menus, double clicking the title bar... nothing worked. I'm using GNOME 3 under Wayland, in case it matters.

I even tried to delete the ktikz configuration file (tried both ~/.config/ktikzrc and .config/Florian_Hackenberger/ktikz.conf) and the window remained undocked!

The exact same problem arises with qtikz (not sure what's the difference between the two, but Debian has both, independently packaged).

With last KDE I have the same issue.

Searching in bugs.kde.org I found a solution. The book seems to be wayland-related. Open a session in X11, open ktikz or qtikz, and move your preview window into the main one, you drop it when you see some light blue background in the window (this is the color in my system). Go back to wayland and it is redocked (till next time you undock it!)
