title: waitForElementToBeRemoved is timing out when passed an element
body: <p>I'm trying to use <code>waitForElementToBeRemoved</code> with just an element but Jest is timing out. When I pass in a function, it works.</p>
  
  <p>My understanding from this feature was that it should be able to take an element: <a href="https://github.com/testing-library/dom-testing-library/pull/460" rel="noreferrer">https://github.com/testing-library/dom-testing-library/pull/460</a></p>
  
  <p>I verified my app is using @testing-library/dom@7.8.0.</p>
  
  <p>Here's the code:</p>
  
  <pre class="lang-js prettyprint-override"><code>// doesn't work
  await waitForElementToBeRemoved(screen.getByText("Loading..."));
  
  // works
  await waitForElementToBeRemoved(() =&gt; screen.getByText("Loading..."));
  </code></pre>
  
  <p>Any idea what I'm doing wrong?</p>
