1. Strange buggy (?) things happened with POST 19464915. The edit log shows: (1) Four characters at the beginning of my reply were removed. I didn't type those char's or do anything with them on editing. I don't know why they were there. (2) I edited in the first place to add the last two words in the post. They were missing the first time. I swear I had included them when submitting.
Those were linefeeds (newlines). Invisible characters.
Answer is: no, reply HUP's are suppressed also. Like HUP's are shown.
What is HUP??
What I'd like is a collapsible HUp. Click/tap to reduce it to a narrow blue band, c/t again to expand it.
My point is that both go to more or less the same location. I mean, there is a dialogue going on, people reply to one another, likes are given and with HU’s for both replies and likes you get links to pretty much the same place.
