Does anyone know where the reference to @types/node is coming from

[jimisaacs]

In the latest published version of this package of 0.9.18: https://registry.npmjs.com/subscriptions-transport-ws/-/subscriptions-transport-ws-0.9.18.tgz

In dist/server.d.ts, you can see this right at the top:

/// <reference types="node" />

Though how is it getting there? I don't see it anywhere in the sources within this repo.

This is causing the node types to leak into our projects based on this issue:
microsoft/TypeScript#31148 (comment)

I've also already commented on this package here:
apollographql/apollo-client#7734

Though I'm confused and would like some clarification.
