Describe the problem

I am developing an animation heavy website with sveltekit where i have a three.js scene in a layout that does some transitioning between pages and also on scroll. The issue I am facing is that when using browser back button and the previous page was scrolled down, i can not do the correct page transition animation because I don't know the scroll offset of the target page. At the moment I transition the three.js scene as if the target page is at 0 y offset and then the scene updates according to the scroll position with a visible disruption.

Repro:

1. visit https://www.morrowsix.de/
2. scroll down a bit and click on one of the two project cards
3. use browser back button

Result: logo in the background scene transitions as if target page was at 0 y offset and then the scenes update function that uses the scroll offset puts the logo in the correct position.

Currently i trigger my transition animation in beforeNavigate

Describe the proposed solution

have the target page scroll offset available somewhere in beforeNavigate and/or afterNavigate

Alternatives considered

I digged a bit in the source and found that sveltekit saves the scrolloffsets in sessionstorage along with an id that can be matched with the history. Before writing a function to extract the information by myself i wanted to ask here if my proposed solution would be feasable to implement upstream.

nice to have
