    without this there is a tiny bug in the current version of next.js - when opening a post (only when there are many posts) for the first time and then clicking on
    the go-back button in the browser, the page (feed) will scroll to the top. FocusTrap's "onDeactivate" is 
    solving this for some reason, but not when opening a post *for the first time*
    see: https://github.com/vercel/next.js/issues/37893#issuecomment-1221335543
