I was looking at this post from my own forum (nBB 4.0.3) via various vectors, and trying to pull it in from here resulted in a couple of hiccups.

1. Searching the posts community.nodebb.org URL did not pull the post and its comments. Naturally, searching the original URL works fine (though does not fetch the comments, naturally)
2. Fetching my comment from that post does fetch the post and full comment chain, but your comment, @julian, is surprisingly empty (link)

Just thought you'd like to know.
