  # Some of our apps have a Cucumber step that changes drivers mid-scenario.
  # It works by creating a new Capybara session and re-visits the URL from the
  # previous session. If this happens before a URL is ever loaded,
  # it re-visits the URL "data:", which will never "finish" initializing.
  # Also when opening a new tab via Capybara, the initial URL is about:blank.

    # the browser environment.

    # We force a non-lazy synchronization so we pick up all client-side changes
    # that have not been caused by Capybara commands.
