List shows empty items after changing store

[A.Tyshchyk]

How to reproduce:
1. Load store with 40 items
2. Scroll to position 20
3. Reload store with 10 items

The problem that list has offset of displayed items (topItemIndex). When the store is loaded, List call refresh and try to render items with offset (topItemIndex). But items with index more than 20 is not exist in store and list render empty items.

There are 2 solutions:
1) Do scrollTo up
2) Set topItemIndex = 0

Is there more better ways?

I would use

list.getScrollable().getScroller().scrollToTop(false)
