Same here, works fine.

Yeah I remember that we had a discussion about docking and undocking, 
AFAIR in the bug tracker (searching.... #38785, see also #37190).

Anyway my conclusion is that Qt's docking/undocking mechanism seems a 
bit flaky (doesn't work properly cross-platform) and/or simply hard to 
get implemented properly - not that I would be able to do it any better :-)

While discussing docking: I see re-docked panes always end up at the 
bottom and get spread over the entire width (I think we once also 
discussed re-docking back into place).
