"this" is undefined in event listeners

[Bauke]

Came across this issue while trying to get HTM + Preact working with Happy DOM:

import {GlobalRegistrator} from '@happy-dom/global-registrator';

GlobalRegistrator.register();

const button = document.createElement('button');
button.textContent = 'A Button';

button.addEventListener('click', function () {
  console.log(this === undefined, this.textContent);
  // Results in: TypeError: Cannot read properties of undefined (reading 'textContent')
});

button.click();
