[Bug] [v2] Changing item span does not work correctly when updating data

[rubenamorim]

Current behavior

Changing the item span has no effect if we update the data of items that have already been rendered.
This was not an issue in v1.

Expected behavior

Changing the item span should be taken into account for all items when updating the data.

To Reproduce

https://snack.expo.dev/@rubenamorim/flashlist-v2-issue

Considering the previous example, where we have a list of items with full-width sections and a button that allows us to remove the sections, when clicking the toggle button to remove the title from the data array, all the items should occupy one column.

That's right! Thanks for reporting this. I'll fix it in the next release.

I've fixed this in v2.0.0-alpha.17. Can you give it a shot and see if it works for you?

[rubenamorim]

I updated the example, and it seems to work as expected, thanks 🙌

Great, closing this.
