`scroll-margin' sometimes doesn't work

1. emacs -Q
2. In buffer *scratch*, C-x C-e:
    (progn
      (custom-set-variables
       '(custom-enabled-themes '(modus-vivendi))
       '(global-tab-line-mode t)
       '(scroll-margin 1)
       '(scroll-conservatively 101))
      (info-emacs-manual)
      (end-of-buffer)
      (goto-line 500))
3. With the cursor now at the 2nd line from the top of the window,
   press <up>-arrow-key several times and pay attention to resulting
   cursor position -- `scroll-margin' is 1 but Emacs still sometimes
   allows the cursor to stay at the 1st line of the window.

I uploaded a GIF at <https://emacs.stackexchange.com/questions/76649>
to show this behavior.

No further comments, so I assume the bug is indeed fixed, and I'm
closing it.
