The line immediately preceding "The named..." has a single space in it. Apparently, this causes this space to be rendered. The editor may be using the newer or different Markdown renderer, for example, which is why you cannot see this space during editing. — Dmitri Pavlov 18 hours ago

I will just add that the character mentioned in the previous comment seems to be Non-breaking space. In case it is useful, you might check what you get for that post from the Posts table and from the PostHistory table. — Martin Sleziak 4 hours ago

Thanks, @DmitriPavlov! That seems to be an answer, so, if you'd post it, then I'd be happy to accept it. — LSpice 10 mins ago

Thanks, @MartinSleziak! I'm not sure how to use the Posts table and the PostHistory table. When I click the links you have supplied, I see one row of a table returned from a query, including the partial rendered HTML of the post, and clicking on the link takes me to the post. How should I extract more information (e.g., the full rendered HTML)? — LSpice 9 mins ago

@LSpice You can simply ignore those queries if they are of no use for you. In any case, I left a few short messages in chat - feel free to ping me there if some additional explanation could help. — Martin Sleziak 23 secs ago

@MartinSleziak, thanks! I in no way meant to imply that the queries weren't useful, only that I didn't know how to use them, but your chat messages addressed that. — LSpice 29 secs ago
