A bit late, but apparently it's still not possible to extend HTMLDivElement. A simple way to solve extending a DIV: just use CSS to make a generic HTMLElement behave like a div.

CSS

 my-element {
    display:block;
 } 

Javascript

class MyElement extends HTMLElement{
  constructor(){
      super()
      this.innerHTML = "I behave exactly like a div"
  }
}

window.customElements.define('my-element', MyElement);
