It's likely this issue predates Contrib.social: some issue and comment data are missing.
This merge should be reverted. Looks like all the Ajax-related core issues have been fixed.
Have you tested 6.2.x-dev with this change reverted and confirmed that it now works correctly?
This should be done as a child ticket.
