Actually the scrolling down part is of the form (scroll-down scrollable),
the origin is here:
https://github.com/emacsmirror/evil/blob/master/evil-commands.el#L870
When `scrollable' becomes 0, the undesired behavior happens.
Another observation is, the undesired behavior doesn't happen under
*scratch* buffer or others alike.
The info mode has sort of a navigation bar, "(elisp)Top > Positions >
