To see the bug navigate to the leaderboard tab in the sink example. Enter a name and see that it appears in the list once. Then, without refreshing, click on home and then back to the leaderboard tab. Add a player and see it appear in the list twice. Navigate away and back again to see that the previously entered player appears only once, but enter a new player and see that it appears three times. Refreshing the page resets the behavior.
i'm closing out issues from before Derby 0.6
