It would be really valuable to implement the
HTTP Cross-Origin-Opener-Policy (COOP)header to ensure that the top-level document does not share a browsing context group with cross-origin documents.The policy to be set in our use case is:
Cross-Origin-Opener-Policy: same-originReference: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cross-Origin-Opener-Policy
Acknowledgments: this tickets follows a discussion had on w3c/webappsec-referrer-policy#159 and some great advices by @annevk and @hackademix! Thank you!
