Did you try adding the following in the XML?
<option name="mapping.map.center">(0,0)</option>
<option name="mapping.map.scrollZoom">0</option>
<option name="mapping.map.zoom">2</option>
Offcourse, you can do it via GUI by selecting the option: Populate with current map settings and then add the mapping.map.scrollZoom to 0
Hope this helps!

Thanks for your comment, but I can't see any effect using these options. Endless scrolling to the left & right is still possible
