  // event back to its opener (i.e., here) with the cookies it received, which
  // we verify against expectedStatus. Then, the test sends a message to the
  // popup, telling it to reload itself via window.location.reload(). Again,
  // the popup posts a message back here with the cookies it received. These
  // cookies are verified against expectedStatusReload.
