payload.toIndex is incorrect

[ftruzzi]

When moving an item to a different container, the toIndex property can be incorrect (maybe when moving over different items on the target list before releasing?)

Below, toIndex should be 1 but it is 3.

Thanks!

I will investigate further, I don't know if it is a problem with Muuri or with Muuri React.

For now if you need the index you can use
toGrid.getItems().findIndex(item => item._component.key === key)
(toGrid is in the payload)
