onIdTokenChanged is called with no reason

[sl0wik]

I'm fighting with this weird, hard-to-reproduce bug where firebase gets into endless loop of a token refresh.

Version

@nuxtjs/firebase: 8.2.2
firebase: 9.6.7
nuxt: 2.15.8

Steps to reproduce

It happened after:

1. Login using app.$fire.auth.signInWithCustomToken().
2. Refresh the page. onIdTokenChanged is being called twice. The second time by asyncToGenerator.
3. Open a new tab with the same page. Both pages will get into endless loop of onIdTokenChanged calls.

What is Expected?

onIdTokenChanged happens only once when the page id is loaded, and onIdTokenChanged is not triggered when the page is opened in another tab.

What is actually happening?

onIdTokenChanged is getting refreshed a second time for no reason, and when the page is opened in two tabs it causes an endless loop of token refreshing.
