Realms no longer says who is online

I believe this bug began at some point in between version 1.15.2 and 1.16, on the realms select screen besides the traffic lights indicating whether or not the world is open there used to be a number indicating the number of people online, and mousing over it would show you who the players were. At some point that number stopped appearing and there is now no way to tell who is on your world.
