Cloudflare Privacy Pass broken attestation

[Technetium1]

It's possible to pass this captcha in Floorp, Chrome, and Firefox. It does not consistently work in Firedragon though. The Silk Privacy Pass extension is blocked from working correctly. The attestation should be happening in the same tab, not opening a new window (repeatedly). The private access token should be generated, and the prompt should not reappear on reload, because the token should be sent when the page refreshes.
