--- Comment #2 from Rafał Mużyło <galtgendo at o2.pl> ---
Well, I'm not quite sure myself...

It's not a matter of the list size, at least not if it's created manually...

There's something funny: on the last 32 items (when list is 90 long), clicking
on the item brings up the item, as for the other items...

First 13 isn't drawn at all, but are navigable with mouse/keyboard blindly.
Once you reach item 17 with the keyboard going down, focus rectangle is drawn
around the item. You can go from 17 to 16 and the focus rect will show up on
16, but not above and not going in the other direction. Above 17, going with
the keyboard works, but mouse clicks select item one below the clicked one. The
mouse/keyboard behavior on the limit between those items and those 32 proper
ones is a bit too difficult to describe.

All in all, it's a mess, but - for the time being - I can quite figure out what
exactly triggers this. I can only say, once it's triggered, it stays triggered.
