[Erik Vold [:erikvold] (please needinfo? me)]

Atm I am trying this:

exports["test Panel"] = function(assert, done) {
  const loader = Loader(module);
  const { Panel } = loader.require('sdk/panel');
  let { document } = getMostRecentBrowserWindow();

  let lastPopup = document.getElementById('mainPopupSet').lastChild;
  let panel = Panel({
    contentURL: URL("data:text/html;charset=utf-8,old-page"),
    onShow: function() {
      let panelEle = document.getElementById('mainPopupSet').lastChild;

      assert.notEqual(lastPopup, panelEle, "the panel element was added");
      assert.equal(panelEle.nodeName, "panel", 'the panel ele is a panel ele');
      assert.equal(panelEle.getAttribute("type"), "arrow", 'the panel is a arrow type');

      panelEle.setAttribute('data-jetpack-test-panel', 'true');
      assert.strictEqual(panelEle, document.getElementsByAttribute('data-jetpack-test-panel', 'true')[0], "the panel element was found");
      panelEle = null;

      panel.contentURL = "data:text/html;charset=utf-8,new-page";
      panel = null;
      done();
      })
    }
  }).show();
};


I get this error:
