I don’t think the limitation is including a quote. I have one instance of a post containing quotes and a backlink to the post I’m replying to in this topic, but clearly there is some limitation other than position that I’ve never run across before.
Quoting doesn’t change the reply target (at least not properly) since you can see your reply to target in the upper left. Discourse tells me it should work the way I describe, but actual use tells me it does not always work this way.
To reply to a specific post in a topic, clicking the grey Reply button at the end of each post and your reply is linked to that post.
If your reply is the next one published after the post you are replying to, this will appear next in chronological order
If yours is NOT next, then two things happen after your post is published:
Your post will include a new link in its header with an image to show what this is ‘in reply to’ - clicking this link displays that previous post for context next to your reply
The original post includes a count of replies at the bottom - clicking this link displays the content of the replies
It did work for me the first time. Or so it seems to me. I am not sure what I did differently, though, if anything, so I am leaning toward there being some other limitations at play. If you know why it worked that once but not any other time, I’d like to know.
Which I tried to do in the previous post (with the useless quote being another post). I tried to reply to your post, then quote another, then quote the post I replied to. Because I had noticed you did that in the post you said “works”. It did not work.
Well, it works for me. I think if you want a backlink in the upper right, it can not be the next post in chronological order, nor already contain a backlink to that post already within the post itself, which it will if you quote from the same post you reply to anywhere inside it.
Your previous post quoting me contains a quote from the post you’re replying to, and so would not work under these rules.
Furthermore, if I go back and edit out the backlink in the quote from my post, the backlink in the upper right hand re-appears. I think that solves the mystery to my satisfaction.
