// Tests the redirect interaction with COOP same-origin-allow-popups and
// reporting:
// 1 - open the opener document on origin same_origin wit COOP
// same-origin-allow-popups.
// 2 - opener opens popup with document on origin popup_origin, no COOP and a
// redirect header (HTTP 302, location).
// 3 - redirection to a document with origin same_origin and COOP
// same-origin-allow-popups.
//
// The navigation (2) to the first document of the popup stays in the same
// browsing context group due to the same-origin-allow-popups COOP of the
// opener.
// The redirect (3) to the final document does since it compares the
// popup_origin/unsafe-none document with the
// same-origin/same-origin-allow-popups document.
//
// A opens B, B redirects to C.
