title: What happens in the browser before the actual functional tests are run
body: <p>When running Intern functional tests in the browser (not headless), I notice that a bunch of different things happen before the tests are actually run. Some things that happen are navigation to different pages, a dropdown with "foo" and "bar", and several other things. Once these finish, Intern then navigates to my webpage and runs the functional tests.</p>
  
  <p>My question is, why does all this happen before the actual functional tests are run?</p>
