--- Comment #12 from Michael Catanzaro <mcatanzaro at redhat.com> ---
Surprise: I checked out the Firefox source code, and it does NOT have this same problem, despite using a newer PDF.js than we do. The problem is still present in upstream PDF.js, so Firefox is doing something differently.

* Check out https://archive.mozilla.org/pub/firefox/releases/130.0/source/firefox-130.0.source.tar.xz
* Open firefox-130.0.source/firefox-130.0/toolkit/components/pdfjs/pdf.worker.mjs
* Search for ";// CONCATENATED MODULE: ./external/openjpeg/openjpeg.js"
* Notice lots of normal JavaScript code rather than the wasm binary that's present in the upstream version

If we could figure out how Firefox has accomplished this, that might present a path forward.
