[Bug]

Description

I was trying to add a google firebase login to multimap example (https://visgl.github.io/react-google-maps/examples/multiple-maps, example is certainly working).

First, i created a empty login with only firebase code,
login name: qiaoxin136@gmail.com
password: 123456
it worked and showed a welcome message, (see login-screen.png)
then i added the multiplemap code, the multiple maps does not show up at all. Nothing. (see empty.png)
I am not sure if there is a bug here or it is google firebase problem.

Steps to Reproduce

the working empty login can be seen in
https://codesandbox.io/p/github/qiaoxin136/login-empty/draft/autumn-pine?workspaceId=d68df01c-f46f-497c-bfee-4134267b36a9

the login with map (showing empty result) can be seen in

https://codesandbox.io/p/github/qiaoxin136/login-map/main?workspaceId=d68df01c-f46f-497c-bfee-4134267b36a9

again login name: qiaoxin136@gmail.com password: 123456

Environment

Compare the working login-empty and login-map CodeSandbox reproductions with the multiple-maps example, then inspect the browser console for the reported Google Maps error. Check whether the map renders after Firebase login and document the relevant library, browser, OS, and Google Maps versions. Done means the authenticated multiple-map example displays its maps without the reported error.
