When I click on either stepper, one event gets passed to
scroll-bar-toolkit-scroll.  It looks like

  (mouse-1 (#<window 3 on .profile> vertical-scroll-bar (5637316 . 7584542) 0 handle))

(There is some variance in the numbers in the (5637316 . 7584542) part.)

So scroll-bar-drag-1 gets called, rather than scroll-up.
