Ask HN: Does Collapsing an HN Thread in a Popular story spike your CPU use?

For popular threads with a lot of comments, collapsing a top comment leads to high CPU usage and can cause browsers (I tried in Chrome and Vivaldi) to freeze up.

For example, this very popular thread: https://news.ycombinator.com/item?id=43561253&utm_term=comment

If you collapse the top comment, I see a huge spike in CPU and my system freezes temporarily.

Is it just me?
