Affected version

Since 27.2

Steps to reproduce the bug

1. Have over 42 subscribtions
2. Refresh subscriptions
3. Switch to "Fast mode" - RSS feeds for subscriptions
4. Refresh subscriptions

Expected behavior

RSS feed updates without 'stops' each 50 subscriptions starting with 42. RSS feeds are not rate limited by YT so this stop just artificially slowdowns the refresh. With bigger amounts of subscriptions it just makes APP almost unusable.

Actual behavior

Both normal refresh and Fast mode have a slowdown for refresh to avoid YT rate limiting and 24h ban, but RSS feeds are not a subject to that rate limiting.
