I’ve got a funky behavior for you, Charles, that doesn’t mess any thing up, but it’s interesting none the less.
In #238, click on the link that opens the dialog that shows comment #88. Then click reply to that comment.
When I do this, the comment at #238 ends up with a green background. This only happens if I click on a link to another comment, and that comment has a private comment section. If I refresh the page it goes away.
I am running on Chrome 96.0.4664.93, but I have seen it before, I just didn’t know what the actual behavior was.
