/**
 * Runs the suite on workerd, the runtime behind Cloudflare Workers, through miniflare. Unlike
 * the browser suites this is a server-side environment, so it neither enforces CORS nor keeps a
 * cookie jar - it should behave like node.
 *
 * `nodejs_compat` is deliberately not enabled: the client has to work on bare workerd, and the
 * flag would let the resolver match the `node` export condition. `compatibilityDate` is
 * required, as workerd refuses to start without one.
 *
 * The one behaviour it does not match the other runtimes on is `on*` handler dispatch;
 * `test/client.test.ts` marks the seven tests that depend on it as known failures.
