conflicting types with @types/node v12

[jsaguet]

Bug Report

I don't know if there is a solution for this since it seems to be linked with @types/node version but I'm reporting it anyway just in case.

Current Behavior
When running karma tests in an angular project using @types/node v12, I get the following conflicting types error:

Error: node_modules/rxjs/dist/types/internal/types.d.ts:17:18 - error TS2717: Subsequent property declarations must have the same type.  Property 'observable' must be of type 'symbol', but here has type 'unique symbol'.

         readonly observable: unique symbol;


  node_modules/@types/node/globals.d.ts:146:14
         readonly observable: symbol;

    'observable' was also declared here.

When switching to @types/node >=13.1.0 there is no error anymore.

Expected behavior
Error should not be present.

Environment

• Runtime: Node v12
• RxJS version: 7.0.0-beta.10
• @types/node ^12.0.0
