"Uncaught SyntaxError: Function statements require a function name" error with firebase/firestore

[jacekkarczmarczyk]

Describe the bug

// main.js
import * as firestore from 'firebase/firestore';

console.log(firestore);

Using stuff from firebase/firestore throws a Uncaught SyntaxError: Function statements require a function name error in the browser

That is not happening with Vue CLI app (so that may mean that it's not a firebase issue), that also didn't happen with vite a while ago (approx. few months, not sure what version I was using at that time, tried to narrow dependencies versions but without success)
