//   expected to map to the created client's id. This is null if there
//   is no such tag, which can happen when the final request was a cross-origin
//   redirect to out-scope, so no worker received a fetch event whose
//   resultingClientId is the id of the resulting client.
//
// In the example above:
// - workers[0] receives two requests with the same resultingClientId.
// - workers[1] receives one request also with that resultingClientId.
// - The cross-origin worker receives two requests with the same
//   resultingClientId which differs from the previous one.
// - Assuming |expected_final_client_tag| is 'x', then the created
//   client has the id seen by the cross-origin worker above.
