Encryption broken on develop.element.io in browsers without WASM support

[jrick]

Description

The Chromium package on OpenBSD disables wasm support by default (for several reasons I won't go into here). It is possible to re-enable it, but I would prefer to leave it off.

The latest development version of Element Web no longer works with this setup. The fallback to loading olm_legacy.js (https://develop.element.io/olm_legacy.js) is 404ing.

Steps to reproduce

• Use OpenBSD chromium, or any other chromium browser with --disable-features=WebAssembly,AsmJsToWebAssembly,WebAssemblyStreaming --js-flags=--noexpose-wasm.
• Open Element Web (currently, Element version: f78be2631ad6-react-1751b4ba43ea-js-acb9bc8cc523)

Logs being sent: no

Version information

• Platform: web
• OS: any (but only tested OpenBSD)
• Version: f78be2631ad6-react-1751b4ba43ea-js-acb9bc8cc523

Normal app.element.io does also not work when disabling wasm support on my side.
