Failed to construct classes with 'HTMLElement' as super

Author: duzyCreated Dec 19, 2020Updated Dec 19, 2020

Traceur transpiled code is looking like this:

javascript

var e,r=customElements,n=(e=HTMLElement,$traceurRuntime.createClass((function e(){$traceurRuntime.superConstructor(e).call(this),this.style="color: red;"}),{},{},e));

From:

javascript

class Foo extends HTMLElement {
  constructor() { super();
    this.style = 'color: red;';
  }
};

And results:

Uncaught TypeError: Failed to construct 'HTMLElement': Please use the 'new' operator, this DOM object constructor cannot be called as a function.

Where this statement fails (the this object is a HTMLElement instance):

javascript

$traceurRuntime.superConstructor(e).call(this)
