[Bug Report/ Suggestion] Users are able to see what friends are playing, despite them having joins turned off

(idk if this is a bug or just a suggestion)
Description: Friends of users with their joins off are able to see what games their friends are playing based off the friends playing sort on the home page. This makes it easier to track people and follow them into games, even if they do not want to be followed in. It also allows friends to view projects of devs that are meant to be kept private from others.

Reproduction steps:

  1. Set up 2 roblox accounts and make them friends
  2. On one of the accounts (a) set “who can join me?” to no one
  3. Enter a game with account (a) and wait
  4. on the second account (b) refresh the page until you see the game in the “friends playing” sort pop up.
