title: Is it possible to assert that the page has stopped scrolling in a waitFor
body: <p>I have a page where I click a "change" link which displays another section.  When this happens, the page scrolls vertically a bit so that the visible section is somewhat centered on the screen.</p>
  
  <p>My next step in the test is to click something inside this newly shown container.  But since the viewport scrolled, the coordinates that geb picks up for the clickable element are no longer accurate and geb tells me it can't click the link.</p>
  
  <p>There's nothing I can assert in the <code>waitFor</code> in terms of visible content.  But I'm wondering if there is a way for me to <code>waitFor</code> the content to stop scrolling?</p>
  
  <pre><code>waitFor { // page no longer scrolling }
  </code></pre>
  
  <p>If not, is there a way to just tell geb to wait a few seconds before moving on to the next event?</p>
