Kibitzer dies when the position is decided

[Lingepumpe]

If you analyze a game with a Kibitzer, if you ever reach a position in which the game is over, typically mate but also stale-mate works, the kibitzer stops showing any lines - which is understandable, as there are no valid moves, the game is over. But if you navigate to other positions afterwards, the Kibitzer remains in this disabled state, no longer analyzing anything. The work-around is to close the kibitzer window and re-open it.

Expected behavior: The Kibitzer should continue kibitzing when navigating back to positions in which there are valid moves.
