Describe the bug

Hi thebe devs and thanks for your software!

Context

We (@bmatthieu3 and I) 're trying to output a jupyter widget (ipyaladin) with thebe-lite.

This widget is written in JS and exports a variable A to window. It works in jupyterlite. See https://cds-astro.github.io/jupyterlite/retro/notebooks/index.html?path=01-intro-to-python-vizier-and-ipyaladin.ipynb

The issue

But with thebe-lite, the widget cannot export A in window and we don't get why. See a live example here :

https://manonmarchand.github.io/draft-thebe-jupyterlite-app/aladin-test

where we get the following issue in the console :

Uncaught (in promise) ReferenceError: A is not defined

And indeed A is not there.
A second run of the cell trying to output the widget gets a different error :

Error: Mismatched anonymous define() module: function(){"use strict";var Zg=typeof globalThis<"u"?globalThis:typeof window<"u"?window:typeof global<"u"?global:typeof self<"u"?self:{};function Tg(B){return B&&B.__esModule&&Object.prototype.hasOwnProperty.call(B,"default")?B.default:B}var NB={exports:{}};/*!
 * jQuery JavaScript Library v3.6.1
 * https://jquery.com/

​Do you know what's happening?

Thanks a lot, and we hope this is the right place to ask the question.

Thanks for reporting @ManonMarchand.

I think this might be the first custom widget we've tried to use with the latest thebe! Just to note that I can reproduce the issue outside of lite using the config thebe: true and running against a local server, which should make debugging a little easier.

Thanks a lot for looking into it!

By the way our custom widget links this app https://aladin.cds.unistra.fr/AladinLite/planets-explorer/ with the notebooks (in case you wanna take a tour on Mars)

🙌🏼 it's a very cool widget, I was checking out some nebula whilst trying to debug earlier 😍
