  51     <p>Before fixing #1631, after klicking Go! no point would have appeared. The Go! button
  52     pans the map over a long distance. Before dragging, the point would have been
  53     outside the valid range, and the pan operation would not have triggered the SVG
  54     coordinate system to be recreated. The new vector rendering takes care of all this. </p>
