The solution here is to provide item keys. Providing a stable key for each item lets Compose avoid unnecessary recompositions. In this case, Compose can see that the item now at spot 3 is the same item that used to be at spot 2. Since none of the data for that item has changed, Compose doesn't have to recompose it.
