clock in game view on hover counts down before clock starts

If you start a game and then, before the first moves are made, hover over your opponent's user name, you get a popup view of the game, and the clock in that view immediately starts counting down even though the actual clock in the game isn't running yet. Specifically, I saw this behaviour in this game: lichess.org/dX4WtuIK81PH

Time stops for none!!

Though I have never noticed that. Will check that out next time.
