// The test
// 1. Creates a same-origin iframe
// 2. Adds to the iframe an unload handler that will
// trigger a request to <unload_request_url>/.../record-header.py...
// 3. Navigate the iframe to a cross-origin url (to data: url)
// 4. Waits until the request goes through
// 5. Verifies Sec-Fetch-Site request header of the request.
