title: Accessing Shadow DOM tree with Selenium
body: <p>Is it possible to access elements within a Shadow DOM using Selenium/Chrome webdriver?</p>
  
  <p>Using the normal element search methods doesn't work, as is to be expected.   I've seen references to the <a href="http://www.w3.org/TR/webdriver/#switching-to-hosted-shadow-doms">switchToSubTree</a> spec on w3c, but couldn't locate any actual docs, examples, etc.</p>
  
  <p>Anyone had success with this?</p>
