When your body isn't scrollable for any reason, the automatic load content behaviour doesn't work. It's because the automatic loading is based on the windows scroll.
Allow setting the scroll element selector.
If "Automatically Load Content" is checked, a new field "Scroll element selector" is show:
Postponed: needs info

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Is this still an issue with 2.0.x? If yes, please update the version and set the status active again with clear steps or (best) with a test showing what's broken.
2.0.x is the active development branch.
If nobody replies, we should assume this is fixed and close this issue outdated.
Thanks!
