[Bug] Can't see comment by author of post in the post (but can in inbox)

https://lemmy.ml/post/48278647

I read the post, I commented, and I got the response from the author of the post as a comment to mine, but when I tap it to go reply to it, in the post I can't actually see the comment at all. It's like it doesn't exist. However, it does show in my inbox, but Blorp can't reply directly from the inbox.

Is this a federation issue or a Blorp issue? I'm not really sure of how this sort of visibility thing works across Lemmy.
