Here's what trips me up: even if I don't display the number, I still need to know whether extra comments can be loaded on that depth. If not I don't want to display a "Load more". You could of course let the "Load more" load hidden comments at any level of that subtree, but I think that causes unexpected behavior.
Maybe this clarifies what I'm talking about:
In the case on the right, there's an unexpected downward shift of content which may disorient the user.
Ah, I wasn’t fully understanding, I see what you’re saying now. There’s no way to know the number of comments on a single level/depth as of now without some extra fetching. I think your best bet at this point would be preloading the next page of comments on the top level, and if no comments are return you then know not to show the “load more” button.
Then, each time the next page of top-level comments is fetched, you can also fetch the children of each comment. This will prevent unwanted layout shift and ensure all children are fetched. If you don’t do this, I’ve noticed sometimes child comments go missing when I try to fetch multiple levels of comments in one request from a larger comment tree (100+ comments)
