+    <h3 id="title">SVG inValidRange Redraw Test Case</h3>
+    <p>Before fixing #1631, after klicking Go! no point would have appeared. The Go! button
+    pans the map over a long distance. Before dragging, the point would have been
+    outside the valid range, and the pan operation would not have triggered the SVG
+    coordinate system to be recreated. The new vector rendering takes care of all this. </p>
