Figured that's the case. Wasn't sure.
That has been that way for over 2 years. Your suggestion in ideasforpoal eventually pushed me to apply it to main comment threads (it was already doing it but only with the left border of the comments.
That's normal. All the related comments are highlighted to show the entire thread from the root comment down to the last child where the mouse is over (or last touch event on mobile).
Oh I understand how it went. I just wasn't positive. I worked in bug testing for many years. If I so come across something I'll say something. Just habit.
