Yes, that workaround would prevent moving tabs and it could be added
with IFDEF LCLQt.
The bug is most likely a regression in recent QT versions. I applied
the change from Zeljko. It uses QTabBar_moveTab and is an improvement
but still does not solve the problem.
I see if I can reproduce it in a small test application.
