Comment 1 for bug 815464

This happens for me as well, both at the top of a list and at the very bottom. Also reproducible is that, if I am at the bottom of a list and scroll back up to the top, short click works fine. However, if I then pull down on the list so that the yellow 'you're at the top of the list so you can't scroll any further' flash happens, short click is then not working when I try again.

Behaviour is exactly as the original poster specified, but hopefully the extra info might help.
