Ask HN: Hacker News Bug? I can not collapse comments

It looks like a long discussion here [1] broke some code responsible for displaying the comment collapsing buttons. I have visited other threads and can see them working but this specific link seems to be broken. The bottom of the page is also missing and that’s probably why the collapsing buttons are nowhere to be seen.
