Fixed #3199

Now the dragged element can be dragged relative to parentNode instead of Window.

Hi, I can see the idea behind the proposed solution. But I'm not sure it works on all situations.
I created a meeting seating plan and I got a weird behavior; items are moving in opposite vertical directions when the drag starts.
I hope you can check this on the vueuse playground and try to move different items vueuse playground OR demo 2

@3aluw I made some changes to the code, and it can make your example run successfully.

Hi, I think it would work well with most use cases.
Can you affirm that it works with local scrolls like this one playground ?
