@NonPlayableClown Posts that didn't federate sooner will show up at the top of the timeline when they eventually get fetched.

There is a Pleroma setting related this, but what it does is stop those posts from going to the top of the timeline by setting a maximum age.

This is how things work, though; the posts are posts rather than a sequence, they're fetched that way. The situation with Revolver won't be much better.
