Mongodb client fails to find when asciidoctor has been required

[viledub]

Hi. I'm seeing a peculiar issue that I've traced to the initial exported function from asciidoctor (line 1 below). If you have a mongo database named "database" and a collection "collectionName" which is not empty, the code below should print out the contents of that collection. But when the asciidoctor require is present it prints an empty array.

I tried this with version 2.2.0 on node 14.15.1

const ad = require('asciidoctor')()
const { MongoClient } = require('mongodb');
const mongoSettings = '?authMechanism=SCRAM-SHA-256&authSource=admin';
const mongoUrl = "mongodb://user:password@localhost:27017"+mongoSettings;
const client = new MongoClient(mongoUrl);

async function main() {
	await client.connect()
	const th = await client.db('database').collection('collectionName').find().toArray()
	console.log(th);
}
main();

I can reproduce this issue.
For reference, Opal is modifying the prototype of base objects. I was able to find the root cause:

const Opal = require('asciidoctor-opal-runtime').Opal
Opal.add_stubs(['$id'])

https://github.com/opal/opal/blob/505fd5d7e899a6766472b302c079b4d383fd8216/opal/corelib/runtime.js#L1315-L1325

The MongoDB client must be using $id but since Opal redefines it, it has a side effect.

I will need to investigate a bit more to see if there's a workaround or a potential fix.
