<title>Cross-Origin-Opener-Policy: a navigated popup</title>
<!-- In particular this is different from coep-navigate-popup.https.html as this document initiates
the navigation (and uses same-origin-allow-popups and no COEP as without that it cannot be
observed). COOP should work identically, but implementations might have used the wrong
authority. -->
