In general, it's up to the browser to maintain scroll position, but given the delay between the page load and PDF load, this may not work correctly. My advice would be to use IntersectionObserver to track which page is currently displayed on the screen, keep it in sync with URL e.g. by adding #page-2 to it, and upon refresh, reading this hash to programatically move the user back to where they were. |
