'before' polyfill error in IE11 #64

Closed fvonellerts closed 5 years ago

fvonellerts commented 5 years ago

There is a small fault in the Node.prototype.before polyfill which results in a ErrorNotFound in IE11.

this.insertBefore(o, this) should be this.parentNode.insertBefore(o, this)

It has already been fixed on MDN: https://developer.mozilla.org/en-US/docs/Web/API/ChildNode/before
