Instead of removing all the attributes manually, wouldn't it be easier to simply
create a new image element and set the attributes we actually want?  I believe
this is just src and srcset. This would replace cloning the element.

Done.

         DomUtil.makeSrcSetAbsolute(ie);
         container.appendChild(ie);

+        DomUtil.stripIds(ie);
+        DomUtil.stripStyleAttributes(ie);
