commit 717aa1ac75ddd54fdf72cd4de6551f1fb536da9b
Author: Andrzej Hunt <andrzej.h...@collabora.com>

fdo#72287 Scroll automatically to show selected item when keyboard used.
806919adf9c9bafbaba92c2d2ab35d2e2f9863f8 added finer-grained scrolling using
the scrollbar / scrollwheel, but inadvertently prevents the display from
scrolling
when an item is selected that is currently offscreen (e.g. by using the
down-arrow
button on the keyboard).
