add support for addEventListener as a no-op

[thescientist13]

Type of Change

• New Feature Request

Summary

At the very least, we should be able to provide a no-op for addEventListener.

Details

So a case like this should not error at least

class MyComponent extends HTMLElement {
  constructor() {
    super();

    this.addEventListener('someCustomEvent', () => { console.log('it worked!'); });
  }

  connectedCallback() {
    this.innerHTML = '<h1>It worked!</h1>';
  }
}
