Firestore and Functions enabled breaks the application with firebase: 8.6.7

[ctwhome]

Version

@nuxtjs/firebase: 7.6.1
firebase: 8.6.7
nuxt: 2.15.6

Reproduction Link

firebase: {
    config: {
      ...
    },
    services: {
      auth: true,
      firestore: true,
      functions: true

    }

Steps to reproduce

Enabling firestore and function services breaks the application. Or at least I haven't been able to make it work. I tried on a new nuxt project and saw the same behavior

What is Expected?

to have access to call functions with this.$fireModule.functions().httpsCallable('functionName');

What is actually happening?

The application stops working if firestore and functions services in the Nuxtjs/firebase services object are both enabled.

this is the error in the console:

client.js?06a0:102 TypeError: e.auth.addAuthTokenListener is not a function

Please downgrade Firebase to "firebase": "8.6.5", and try again, the newest v8.6.7 seemed to have introduced this bug.

I assume they will fix it in the next update.

I am getting session.auth is not a function by reverting to firebase@8.6.5. firebase@8.4.3 works.
