title: Failed to execute $$ on 'CommandLineAPI'
body: <p>I'm getting an error that I haven't seen before and not sure as to why</p>
  
  <p>I'm looking for a specific element on a page using jQuery</p>
  
  <p><code>$(".bmr-dropdown-menu-item__text")</code> works as expected. However when I try to search the innerHTML of all of the results using <code>:contains()</code> I get an error.</p>
  
  <p>What am I doing wrong?</p>
  
  <pre><code>$(".bmr-dropdown-menu-item__text")
  &lt;span class="bmr-dropdown-menu-item__text ng-binding"&gt;Cold Prospect&lt;/span&gt;
  $(".bmr-dropdown-menu-item__text:contains('Cold')")
  VM4277:1 Uncaught DOMException: Failed to execute '$$' on 'CommandLineAPI': '.bmr-dropdown-menu-item__text:contains('Cold')' is not a valid selector.
