This javascript function seems to be the cause of the loop problem. Any ideas on modification of this code or an alternate css / html approach to full size iframes?
$(function(){
if($.colorbox) {
$('.lightbox').filter(':not([href*=lightbox\\=0])').colorbox({iframe:true, width:"100%", height:"100%"});
$('svg .lightbox').on(clickEv, function(){
$.colorbox({iframe:true, width:"100%", height:"100%", href:$(this).attr('xlink:href')});
return false;
});
$('.thumb').colorbox({maxWidth:"95%", maxHeight:"95%"});
}
});
