Working on fixing this test, at the moment overlayEl does return the button element, but the drillSpy is not called in test. After the ENTER key event has been triggered.

I wasn't able to fix this test too. It looks like in Chrome the synthetic keyboard event for enter doesn't trigger "click" handler, but a trusted keyboard event does. So this won't work:

const event = new KeyboardEvent('keydown', {
  key: 'Enter',
  code: 'Enter',
  which: 13,
  keyCode: 13,
});
mybutton.dispatchEvent(event);

We could add an event handler for Enter (and also Space), or just trust in browser behavior, and leave it untested.

Yeah seems fine to skip this test, as the browser will trigger the click event on a button element by default on ENTER key event.

}
));
