Steps to reproduce the issue

In Joomla 3 pagination links are handled on the server as explicit separate URLs in the form <URL>?start=X.
In Joomla 4 with Cassiopeia template, pagination is done via javascript on the browser
onclick="document.adminForm.limitstart.value=X; Joomla.submitform();return false;">
so navigating to page 2, 3, ... keeps the same page URL

Expected result

Crawlers expect to find different content to different URLs.

Actual result

Completely different contents are associated to same URL.
Isn't that super confusing for crawlers/SEO?

System information (as much as possible)
