Unfortunately, not. I initially get whitespace where the scrollbar
should be. If I change the theme a few times, I eventually get stepper
buttons, but the slider is included, and it all extends down into the
second window (see attached). (This is with the emacs-26 branch, built
July 4.)

I've attached 2 logs from the gdb session. The first was after using
your original instructions. The second was from using (- 3 ...) instead
of (- 2 ...). (In the second case the scrollbar was visible, but again
it extended into the lower window.)
Let me know if I messed something up or there is additional data you
need.
thanks,
mike
