useWindowAsScrollContainer should not crawl to root node

There is an issue with grid and `useWindowAsScrollContainer`. It should not be crawling up to first `overflow: scroll|auto` DOM element. As seen in `getScrollingParent(this.container)`. Result is something like this using grid layout:

Or we could get a `prop` of some sort for grid layout when scroll is not used at all?
Like `isScrollable` and then this code:
```
this.scrollContainer = useWindowAsScrollContainer
? this.document.scrollingElement || this.document.documentElement
: getScrollingParent(this.container) || this.container;
```

becomes

```
if (isScrollable) {
this.scrollContainer = useWindowAsScrollContainer
? this.document.scrollingElement || this.document.documentElement
: getScrollingParent(this.container) || this.container;
} else {
this.scrollContainer = this.container;
}

```

Currently `animateNodes` inside `SortableContainer.js` does transformation and calculation ends up `this.containerBoundingRect` having to be root element (most websites has overflow scroll somewhere, right?).
`edgeOffset.left + translate.x > this.containerBoundingRect.width - offset.width`

Current workaround, if you want to have non scrollable, simple grid box layout and draggable list is to add `
