Or there is no bug at all: with invisible text followed by an overlay with an after-string you can't put point to the beginning of the Info buffer - probably for a reason. OTOH, using more reasonable =E2=80=98dis= play=E2=80=99 allows point to move to the top of the window, so perhaps this is why scrolling works in the latter case but doesn't work in the former one.
