Description

On a site with cross-origin-embedder-policy: require-corp it is not possible to sign-up using email as turnstile fails to load with:

GET https://FRONTEND_API/cloudflare/turnstile/v0/api.js?render=explicit&_clerk_js_version=4.68.1 net::ERR_BLOCKED_BY_RESPONSE.NotSameOriginAfterDefaultedToSameOriginByCoep 200 (OK)

Reproduce

1. Ensure site has cross-origin policy headers set
2. Bring up the sign-in popup, e.g. Clerk.openSignIn()
3. Click "Sign up"
4. Enter valid email address and password
5. Click "Continue"

See error:

Sign up unsuccessful due to failed bot validation. Please refresh the page to try again or reach out to support for more assistance.

Workaround

Manually add a script tag with crossorigin="anonymous" attribute, this works because the captcha loader checks if window.turnstile exists and if so does not try to load it again.

Potential fix

I think it can be fixed by passing in crossOrigin: 'anonymous' in captcha.ts as that should do the same thing as the workaround.
