// 2. In early_hint_asset_html.sjs, a 103 response with
// a Link header<early_hint_asset.sjs> and the provided uuid is returned.
// 3. We use "http-on-opening-request" topic to observe whether the
// early hinted request is created.
// 4. Finally, we check if the request has the correct `isPrivate` value.
