This was due to an incorrect feature ID being used. I've reconfigured the experiment recipe and it seems to be working now.

We verified this issue and can confirm it's no longer reproducible. We managed to enroll successfully in the experiment using Firefox 113.0 (Build ID: 20230504192738) across OSes (Windows 10 x64, Linux Ubuntu 20.04 x64, and macOS 12.6.1). Considering this, I will mark the issue as Verified Fixed.
