Gear button on pile not working

[buuhuu]

When I click the gear icon in the pile here https://main--exlm--buuhuu.hlx.page/en/dirk-demo nothing happens.

That seems to be related to this piece of code: https://github.com/adobe/aem-experimentation/blob/main/src/preview.js#L52-L75

  const actions = typeof header === 'object'
    ? (header.actions || []).map((action) => (action.href
      ? `<div class="hlx-button"><a href="${action.href}">${action.label}</a></div>`
      : `<div class="hlx-button"><a href="#">${action.label}</a></div>`))
    : [];
  // ...
  const buttons = [...popup.querySelectorAll('.hlx-popup-header-actions .hlx-button a')];
  actions.forEach((action, index) => {
    if (action.onclick) {
      buttons[index].addEventListener('click', action.onclick);
    }
  });

While the only item in header.actions has an onclick handler, the html string in the actions array does not.
