Comment 5 for bug 1238979

I agree that accidental activation is a problem. It's not nice if I tap something only to find that, a split second before my finger touched the glass, the list was updated and I've activated something else.

If we animate new items into view, we have to make sure that a new item cannot displace an already-displayed item. Otherwise, if I have, say, five items on the list and I want to activate the fifth item, and now a new item slots in a position 3, shifting everything below it down, I'll end up accidentally activating the fourth item.

I think the key to making sure that accidental activation doesn't happen is to enforce that an existing item cannot change physical location when a new item arrives.
