We use || attrName because IE doesn't seem to support .localName see

Thanks for your feedback, very appreciated.
About which version of IE are we speaking? (IE9 supports localName, see).
Microsoft officially stopped to support old IE versions until version 11

My point is that the setAttributeNS API is called with the wrong argument and I provided the official W3C specifications. May I ask you to study them yourself, look up all the technical definitions in the official DOM API glossary and then decide for yourself if I'm right or wrong.

fromValue = fromNode.getAttributeNS(attrNamespaceURI, attrName);
var attrLocalName = attr.localName;

// Important: getAttributeNS expects the localName of a namespaced attribute
// ref: https://dom.spec.whatwg.org/#dom-element-getattributens
// ref: https://www.w3.org/TR/DOM-Level-2-Core/glossary.html#dt-localname
fromValue = fromNode.getAttributeNS(attrNamespaceURI, attrLocalName || attrName);
if (fromValue !== attrValue) {
// but setAttributeNS requires the fully qualified name
