Most SPA infinite scrolls break the "Back" button—users click a post, hit back, and lose their position. Many devs switch to pagination just to avoid this headache, even when infinite scroll offers a better UX.

This demo shows a "Save and Restore" approach that makes web lists feel native:

* State Persistence: Caches currently loaded records and the scroll offset before navigation. * Instant Hydration: On back-navigation, it checks for cached state to re-render the list immediately. * Precise Restoration: Snaps the user back to their exact scroll position without layout shift.

I'd love to hear how you all handle this in your apps.
