Single recursion of that backtrace

Unfortunately there is no start in the long backtrace. I would happily blame
this on QtWayland bugs, if you can't repo on X11, not that this would help the
bug reporter ;-)

While the loop is quite tight (just 21 frames), and the Qt5 code is even just
10 frames of it (the rest is generic VCL code, which is less likely to be
wrong), I'm not sure where to resolve the chicken-egg problem... guess it's
just too late today.

OTOH after reading all the platform implementations of SalFrame::ToTop multiple
times, I still don't understand, what these ToTop flags really mean, so that
VCL Qt5 code is probably still buggy...
