Ask HN: Bounty – iOS doesn't hold my scroll position when going back to HN

Do you click the "hide" links to hide submissions?

The visual hiding is done via Javascript when you're viewing a page. What seems to happen is that when you hit the back button, Safari asks HN if the page has changed, and HN says that it hasn't. This is untrue because you've hidden submissions. But because HN says it hasn't changed, Safari re-displays the page it has cached in memory and restores where the browser viewport was - but doesn't restore the DOM state, i.e. where your hidden submissions were 'recorded' in the browser.

Hence if you've hidden submissions above where the viewport was, when those submissions reappear, it pushes the subsequent submissions down, and the viewport ends up above where you'd expect it to.

There's no client-side solution for this.
