This PR fixes issues where rendering a new parallel route would reset the scroll state of the page. This would be very apparent if you scrolled down the page and opened a modal in a parallel route. After a bit of investigating, I found out that the scroll behaviour worked like this: - after a navigation, we say to the router that we should auto-scroll if possible - but we don't specify which node of the tree should scroll - so what happened is that the first router node to run the auto-scroll effect would steal the auto-scroll, even though it might have been destined for another node The fix consists of - when we received the flight patch, we compute all new segment paths that will be rendered and add them to the scroll ref - when the router says that we should autoscroll, the autoscroll components will now read those paths and compare them with their segment path and if yes, they will autoscroll <!-- Thanks for opening a PR!
