Re: [WICG/webcomponents] Can ElementInternals have ARIA properties pointing inside the shadow root? (Issue #974)

@annevk Thanks, you're right, I was not thinking this through clearly. A better example would be using `ariaDescribedByElements` instead:

```js
class CustomElement extends HTMLElement {
  constructor() {
    super()
    const element = document.createElement('div')
    element.textContent = 'My description'
    this.attachShadow({ mode: 'closed' }).appendChild(element)
    this.attachInternals().ariaDescribedByElements = [element]
  }
}
```

As for the `aria-describedby` IDREF, I agree it makes more sense for the ID search to happen within the document or shadow root containing the host element, since ElementInternals is attached to the host element, not the shadow root.

 (I also fixed my original example. `ariaDescribedBy` is not even a reflected property; my bad.)
