Probleam with SVG link - Issue #394

Before, there were javascript errors when clicking on a link from SVG.
When attempting any movement touch screen, meant that other movements
were no longer detected. This update fixes this problem, since the links
are SVG object and not a string.
change classList to string (no value)
