Class extends value #<Object> is not a constructor or null using ws library with SSR with cloudflare preset

Environment

• nuxt: 3.0.0-rc.12
• nitro: 0.6.0
• node: 16.15.0

Reproduction

https://github.com/vptill/not-a-constructor

Just create a new nuxt project, add SimpleDDP client as a plugin and build the application. It only fails with SSR and Cloudflare workers, SSG and dev work fine

• Clone the repository
• Run yarn (or npm install...)
• Run yarn build
• Run npx miniflare .output/server/index.mjs --site .output/public

Describe the bug

The application builds successfully, but the SSR server generation with cloudflare preset fails with the error: Class extends value #

Putting in nuxt.config.js alias: { ws: 'isomorphic-ws/browser.js' }

Solves the issue, however, it won't work on Cloudflare pages, because cloudflare has an unique way to handle websockets currently.
