Describe your project's tooling

typescript project, with "exactOptionalPropertyTypes" enabled in tsconfig.json.

Describe the problem

The project does not compile and gives the following error:

node_modules/@firebase/app/dist/app-public.d.ts:201:26 - error TS2430: Interface 'FirebaseServerAppSettings' incorrectly extends interface 'FirebaseAppSettings'.
  Types of property 'name' are incompatible.
    Type 'undefined' is not assignable to type 'string'.

201 export declare interface FirebaseServerAppSettings extends FirebaseAppSettings {

With exactOptionalPropertyTypes the both declarations of name are not compatible (see https://www.typescriptlang.org/tsconfig/#exactOptionalPropertyTypes).

This is actually a duplicate of #8227, but I was unable to comment on the original issue and wanted to provide a minimal reproducible example (see below)

Steps and code to reproduce issue

1. Checkout https://github.com/ansf/firebase-8227-mre
2. npm i
3. npm run compile

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @ansf, thanks for reaching out to us. I was able to reproduce the error using your code. I'll communicate this with our engineers and bring someone here that can provide more context about it. I’ll update this thread if I have any information to share.
