Incorrect behaviour for Link header
When a user has no more statuses, on
Link header is given. Mastodon, instead, gives only a
link: <https://mstdn.io/api/v1/accounts/96921/statuses?exclude_replies=false&since_id=99740919846633556>; rel="prev" header, where since_id is the ID of the first post returned. I'd take the guess that this is what causes mastofe#9 (closed) to happen.
