[iOS] - CollectionView V2 layout problem

### Description

With the CollectionView V2 handler, I have a layout display problem. When loading an item into the collectionview that has a footer, it seems that the item resizing (due to a change in a property) causes the item to overlap the footer. When doing a pulltorefresh, the situation is corrected

2. first time, the item and the footer are wrong
