  // Allow for:
  // - root-relative URIs (e.g. /foo.jpg in http://example.com/foo.jpg)
  // - protocol-relative URIs (e.g. //bar.jpg, which is expanded to
  //   http://example.com/bar.jpg by the browser when viewing a page over
  //   HTTP and to https://example.com/bar.jpg when viewing a HTTPS page)
  // Both types of relative URIs are characterized by a leading slash, hence
  // we can use a single check.
