code-server rendering in Firefox desktop

Description

The Continue window does not seem to be rendering correctly in code-server via desktop Firefox. This was tested in both the current release and pre-release versions. I confirmed that it is rendering correctly in Safari and in Firefox for iOS/iPad OS - it just seems to be isolated to the desktop version. For further isolation, this was still happening in a private browsing window with all Firefox extensions and all code-server extensions (except Continue) disabled.

I've included the browser console logs below after a fresh refresh and opening of the Continue window. Let me know if any more specific logs would be useful.

To reproduce

1. Open Continue window in code-server on desktop Firefox

Reproduce the Continue window in code-server v4.112.0 on desktop Firefox, using the reported macOS setup and a private browsing window. Start with the browser console logs, especially the 404s for vsda.js and vsda_bg.wasm, and compare the result with Safari or Firefox on iOS/iPadOS. Done means the Continue window renders correctly in desktop Firefox without the reported failure.
