Auth persistence fails in Safari

### [REQUIRED] Describe your environment

* Operating System version: macOS Monterey 12.2.1
* Browser version: Safari 15.3
* Firebase SDK version: 9.6.8
* Firebase Product: auth

### [REQUIRED] Describe the problem

The problem arises in Safari auth sessions lasting 1 hour or more.

* Calling `getIdToken()` or `reload()`, passing in the result of `getAuth().currentUser`, throws an error `undefined is not an object (evaluating t._canInitEmulator=!1)`.

* On calling a Firebase HTTPS Callable function, the auth token also fails to validate. `context.auth` evaluates falsy.

* When inspecting `firebaseLocalStorage` contents in Indexed DB, `value.stsTokenManager.expirationTime` is not updated.

Note that `getAuth().currentUser` returns a `User`.

(We do not explicitly specify authentication state persistence, so assume it is the default 'local'.)

#### Steps to reproduce:
1. Sign in
2. Leave session open for 1 hour +
3. Call getIdToken() or reload(), or call HTTPS Callable function
