Can not call super?

[retrocausal]

I defined a class for a custom div element like so:

class myAwesomeDiv extends HTMLDivElement{

  constructor(){
    super();
    this.addEventListener('click',e=>this.toggleFav());
  }
 toggleFav(){}
}

and on using it as <awesome-div></awesome-div> ,

I am seeing this (line 82 in app.js is the call to super())

You can't extend HTMLDivElement right now. We'll be adding customized built-in elements support soon.

thanks @justinfagnani . Is there a list of elements currently supported?

[justinfagnani]

Only HTMLElement

are you still working on it?

i need self defined input and textarea elements in forms ;)

[justinfagnani]

We're still in a situation where we have no native implementations of customized built in elements. That may change soon...

It seems like Chrome supports it as far as I can tell. I would love to have access to this feature via a polyfill so I can extend the functionality of a textarea.
