I have a UICollectionView that has several columns (each corresponding to a different section). Each of these columns has several cells, each with an independent height. I have implemented drag and drop of cells for reordering and it is working correctly, but the preview of what will happen after I drop a cell does not match with what actually happens. I believe this is because the cells that are being moved as a result of the drop proposal are moving down in their column and taking the layout attributes of the cell that was previously at that index path (it has now moved down as well). You can see a gif of what this looks like on my stack overflow post (I haven't gotten any responses): https://stackoverflow.com/questions/64094070/collection-view-different-sized-cells-with-drag-and-drop I am using a diffable data source and compositional layout, if that helps. Any help is appreciated, thank you!
