### Issue Tracking Info

- [X] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Start by inspecting fido2-page-script.js around line 449, where navigator.credentials.create is assigned, and reproduce the issue in Firefox DevTools using the listed browser and build versions if available. Done means opening any page and the Browser DevTools without the read-only TypeError appearing in the console.
