Users - Active or not?

Sat 12th Feb 2022 I logged in. I managed to get to the URL https://livebeats.fly.dev/anujmiddha although I can't remember how I got there, since there were no ACTIVE USERS listed for me to click on (see screen shot below).
I could hear the music intermittently ie on for a while, stopped for a bit, as if user anujmiddha was actually active (and listening, but switching between play & pause).
Furthermore, I noticed upon inspecting the screen shot that the ping ms is not visible on my avatar nor the other users.
(all tests on Mac 11.5.2 Firefox V96.0.3)

Start by reproducing the report at https://livebeats.fly.dev/anujmiddha using the listed Firefox and macOS versions, then inspect the active-users listing and user avatars shown in the screenshot. Check whether the reported user appears, whether ping values are visible, and whether playback remains consistent; done means these reported behaviors are resolved.
