I think the steps are incorrect. The problem is not when selecting the 
last entry in the list, but in selecting the last visible entry, where 
there are more entries following that can be scrolled to. Reproduced in today's 
verification build on Win98. Happens with bookmarks in sidebar too.  putting on 
beta1 radar, assigning to hyatt as p1 for M14

Yes, you are correct, I meant the last visible entry.

Fixed, oddly enough, by my partial fix to #26618.
