Why does page turning in the bottom block (bottom pagination) not work correctly on Prestashop in Opera and Chrome?

Question

Prestashop

Switching works, but not as we would like.
for example, the client is on this page, flips through the page with products to the very bottom. Clicks on the second page and remains all the same at the bottom. And I would like it to be redirected to the very top of the page. Like, for example, here.
I note that there are no such problems in Internet Explorer and Firefox.
Problems are observed only in Opera and Chrome.
Tell me what could be the problem?
I suspect that the problem may lie in the blocklayered.js file, but I do not understand what exactly is wrong there.
