I managed to get if fixed with a small hack in the jquery_plantuml.js file.
I modified the done_deflating function and the world is all beautiful. I paste the code below in case someone else finds it useful. This allows for SVG files to also be clickable from within the browser. The trick however is that the canvas loading the img should have "svg_canvas" as its id. Maybe a quick hack, but works fine.
function done_deflating(e) {
var done = 0;
$("img").each(function () {
if (done==1) return;
var u1 = $(this).attr("src");
if (u1!=null) return;
var u2 = $(this).attr("uml");
if (u2=="") return;
$(this).attr("uml", "");
var svgObj = document.createElement('object');
svgObj.setAttribute("type", "image/svg+xml");
document.getElementById("svg_canvas").appendChild(svgObj);
done = 1;
});
plantuml_runonce();
}
