FlatList re-mount all the row when using columns

Description

Regardless of the use of optimization techniques, such as React.memo or useCallback, when a FlatList with columns (numColumns > 1) is created and an element is added or removed from the list, this causes all components of the row where the element was added or removed to be re-mounted. This is easily noticeable if entry animations are used (but it has other serious repercussions). I'm currently stuck in development on this issue (and switching to unsare scroll view would make the app unusable). There are many similar issues by now, all closed without any discussion or solution, and since it has been years now I think it is time to take the problem into consideration.

Steps to reproduce

1. configure a Flatlist with numColumns > 1 2) add dynamically a new item or remove an item 3) all the items of the row addicted are re-mounted

Bắt đầu với trình tái hiện Snack được liên kết và cấu hình FlatList sử dụng giá trị numColumns lớn hơn một. Tái hiện thao tác chèn và xóa, đồng thời quan sát việc mount các hàng trên Android và iOS. Được coi là hoàn tất khi các mục hiện có của hàng bị ảnh hưởng không bị mount lại trong các lần cập nhật này và hành vi đã được xác minh trên phiên bản React Native được báo cáo.
