Question regarding List Item not re-render when renderItem changes

[mk-nickyang]

Hi team, I only started using FlashList recently and noticed List Item does not re-render when renderItem changes. Please see the example below.
https://snack.expo.dev/@lucissa/shopify-flashlist-renderitem
(renderItem gets updated when the time state updates, but List Item still shows the initial time)

Some existing issues are already related to this (e.g. #585, #505, #566), and the solution provided is to use extraData to force an update.

So I want to confirm if List Item not re-render when renderItem changes is an expected behaviour. If so, I'm wondering if this should be mentioned in the docs since it's different from the RN FlatList behaviour. And I assume we also don't need to memoizing renderItem, keyExtractor etc. when using FlashList if that's the case?
