Settings > Apps > Safari > Reading List: Automatically Save Offline

“Save webpages to read later in Safari on iPhone” https://support.apple.com/guide/iphone/save-pages-to-a-readi...

You're just adding a step that doesn't fix the primary issue (you can already manually save any page you want without adding it your reading list). Someone should be able to go to their translate app, then their photo galley, and back to Safari without it needing to refresh the context.

That doesn’t save the current dynamic state of the page. It’s at most useful for static content, but even on a Wikipedia page you’ll lose your current state of expanded/collapsed sections and hence your reading position.
