Undici fetch hangs forever when concurrently fetching many requests, using node-fetch works

[remorses]

Describe the bug

Using unframer a tool that fetches js modules and bundles them with esbuild, hangs forever in Stackblitz because fetch calls never finish

From my testing this is caused by fetch, if i switch to using node-fetch, the command ends succcessfully.
