[Bug] Infinite scroll in multi-user timeline
It seems that infinite scroll + multi user timelines are broken, not loading more tweets after scrolling the first page of tweets

steps to reproduce:

1. open [nitter.net](http://nitter.net/)
2. go to preferences
3. enabled "infinite scrolling"
4. load this list [nitter.net/nasa,spacex,esa](http://nitter.net/nasa,spacex,esa)
5. scroll past the first page
