Realtime doesn't allow to accept group or friend request

[kukutz]

1. Any OS and browser, tested in Yandex Browser 20
2. Main frontend at freefeed.net
3. Let's user U1 created private group G1 and have freefeed open in browser. Then user U2 requests a subscription.
4. U1 will receive notification by realtime "U2 sent a request to join G1 that you admin" - OK.
5. But it doesn't follow by button Review, there's no blue box on main page "You have 1 group subscription request" and there's no request at https://candy.freefeed.net/friends?show=requests, U1 will receive all three items (button, blue box, request) only after fresh load of freefeed page.
