The algorithm doesn't know about the nature of the function you're trying to contour. It sees values changing sign across the y-axis, and without knowing that it's actually a discontinuity it assumes that the function must be zero along the y-axis. I think this will be the case with any contouring algorithm that just takes in a matrix of numbers.
Maybe we can put in an option where the algorithm will treat value jumps larger than some input parameter as a discontinuity? I'd rather handle cases like this by filtering out the contours lines afterwards, but it's not difficult to add this extra parameter in if there's enough people needing this.
