I guess Sentry doesn't route the URL here properly.

Shouldn't https://github.com/getsentry/sentry-javascript/blob/d381ace59eece2697925b6430af0091e9589503b/packages/core/src/api.ts#L52 be using the host name from the DSN to generate the URL to fetch the error page from? I can patch the server for this, but I would have thought that the DSN would have been enough to get the correct behavior here.

The fix for the server endpoints has been deployed, this scenario should be working now for EU organizations.
