/**
A flag indicating that during section reloads, if the number of items for the section is unchanged, we should
prefer to generate item reloads instead of treating as "delete section, then insert section" operation.
Instead, we would generate updated indexPaths to be used in `-[UICollectionView reloadItemsAtIndexPaths:]` during updates.
@note If the number of items for the section is changed, we would fallback to do the "delete section, then insert section" operation.
A flag indicating that section reloads should be treated as item reloads, instead of converting them to "delete, then insert" operations.
This only applies if the number of items for the section is unchanged.
@note If the number of items for the section is changed, we would fallback to the default behavior and convert it to "delete + insert",
because the collectionView can crash otherwise.
Default is NO.
