But scroll down. As you scroll down, the line of minus signs grows. When you are 6 comments deep into a conversation (where each comment is a reply to the last. The comments are all indented to the right), there is a line of 6 minus signs at the top left (------).

If you click on the second minus sign on the left, it collapses the conversation up to that parent without having to scroll up to that level.

I see! I can see the - signs but clicking them does nothing...

Yeah, I had this problem too on one page. I clicked on another article and it worked. Looks like it is a little buggy (founder take note!)

Yes, I am aware of the issue (see my recent comment on one of the parent comments).

I am afraid that it is an issue with the way some browsers render the CSS sticky position. If you have any CSS knowledge, I would greatly appreciate your input!

For my information, which browser do you use?

I tried both Google Chrome and Firefox (also, Brave)
