And it took me 2 minutes clicking around to break its idea of the page state. I am partially scrolled down the home page, and it just decided to deactivate scrollbars and the ability to scroll.

A great example of how it's quite difficult to reimplement stuff that works perfectly well on traditional pages.

(At least they seem to haven gotten rid of some of the dark patterns they had in the past, that's nice to see)

EDIT: and within a minute more found another state bug :D

Yes, you can make perfect SPAs, but many people fail and it's a good question if the effort required to do it properly is worth it.
