Document references from another DB cause error logs about firebase-js-sdk HOT 2 OPEN

Hi @tzappia. Thank you for reporting this issue. I'm able to reproduce it and I can see how it would be a nuisance.

Here are the steps that I followed:

1. Extract firestore_export_data.zip to a directory on your local computer.
2. Start the Firestore emulator: firebase emulators:start --only firestore --import 2024-04-19T16:22:17_20757 (the path to --import is the directory that was created upon extracting the zip file).
3. Run a query in the collection EmulatorImportIssue8166.

Expected Results:
No warnings are logged.

Actual Results:
The following warning is logged to the console: Document EmulatorImportIssue8166/DocA contains a document reference within a different database (dconeybe-testing/(default)) which is not supported. It will be treated as a reference in the current database (foo-bar-baz/(default)) instead.

Here is some sample code to run the query:

const db = getFirestore();
const collectionRef = collection(db, "EmulatorImportIssue8166");
const snapshot = await getDocs(collectionRef);
for (const documentSnapshot of snapshot.docs) {
  console.log(`Document: ${documentSnapshot.id}: ${JSON.stringify(documentSnapshot.data())}`);
}

I've logged b/335854401 to track this request internally. Note, however, that I can't make any promises as to if or when we will fix this. But we will reply back if there is any progress.
