It works - goes back in history, url changes.
But page content stays the same.
It's about switching between # pages (1, 2, 3, etc). Going back before library works.
Not sure if i missed any paginated pages, no idea about My MDlists/Groups since they're empty, one outlier is the series page with the chapters though, it doesn't get the ?/&page in the url so it just yeets you out
It's not just for goes back history, It also happen when open in new tab, when trying to open page 2 in new tab it just goes to page 1 even tough it have the page=2 in the url
