There's an issue happening when you change points after having activated the gesture once. The onPointSelected callback is executed even though there's no gesture active at the moment. You can see the problem in the video below. You'll notice that the current price changes to a "random" value that's actually what's being passed to onPointSelected when the points prop change.

After the fix, the behavior is what I believe to be expected: the onPointSelected callback is not called after changing the points.
