Binding scrollY to `svelte:window` causes implicit scrolling to the top of the page about svelte HOT 6 CLOSED

This is already fixed in the latest version of 5.0-next, make sure to update the version.

@dummdidumm https://stackblitz.com/edit/vitejs-vite-f8dfha?file=src%2Froutes%2F%2Bpage.svelte - no, you're right, there is no bug in Svelte 4.

@dummdidumm Can you tell me if this change will be reflected in Svelte 4? If not, it might be worth mentioning it in #11400. Thanks!

Does the bug even exist in Svelte 4?

@dummdidumm But I found another related bug:

• Svelte 5 (runes) - initial value of the bound scrollY is undefined. 🔴
• Svelte 5 (no runes) - initial value of the bound scrollY is undefined. 🔴
• Svelte 4 - initial value of the bound scrollY is undefined, then 0. 🟢

@dummdidumm I found the issue again in my app. The example this time is a little more complicated:

• https://stackblitz.com/edit/vitejs-vite-3yda5w?file=src%2Froutes%2F%2Bpage.svelte - the problem is not consistently reproduced on StackBlitz.

Any deletion fixes the issue (e.g. if you remove class="relative grid overflow-clip" / <div bind:contentRect></div> / <svelte:window bind:scrollY /> / scroll-behavior: smooth;...).

Svelte 5.0.0-next.135 🟢 - when refreshing, the page scrolls smoothly from the beginning to the position where it was before the refresh.

Svelte 5.0.0-next.136 🔴 - when refreshing, the page instantly scrolls to the beginning and stays in that position.
