Hey, thanks for that, it works (although I need to find some time to read it properly and understand why mine wasn't) except an error when you're in a page that is not a topic page.

I'll merge it and add a check so that it run only when in a topic's page that is where we've the issue anyway :)

Error when not in topic's page, can be solved with a simple IF that encapsulate the logic. Will add myself after the merge.

The gist of it is that you were listening on document.body, but the comment elements are too deep in the DOM to be picked up by that. If you enabled subtree: true it would have worked, but it would be pretty inefficient - so I listened on the parent element of the comments.

got it, i thought that child (or however that setting was, maybe childrens) was enough to have it iterate through the whole thing.

However yeah, it would have been definitely not optimised, thanks again!
