Someone who hasn’t used Facebook for over 6 years, I’m still trying to convince my grandfather that I don’t actually know anything about the platform and that he probably knows more about Facebook than I do. cause honestly I don’t recognize it anymore
Someone correct me if I’m wrong but, I think you are right on the bug, I don’t think this is an app specific, I’ve had the same thing happen when browsing my main instance via it’s web portal and on jerboa and connect as well. I agree there’s a bug with Lemmy itself in regards to comment trees.
edit: it appears there is an issue report out for it on lemmy-ui: here and here
