from 11.1.0 version and above the behavior of dropping item changes for my custom scenario.

I have two CollectionView's. one on left has inner collectionview, and one on right. When the inner collectionview has no items, dropping item from the right collectionview to the collectionview with no data cannot be achieved. 

The height of the inner collectionview with no items is 0. 

This works in 11.0.0 version but after 11.1.0 the behavior changes and item cannot be dropped.
