Description
Jetpack Compose component(s) used:
* LazyColumn
* PagingSource (for paginated data loading)
Android Studio Build:
* Ladybug Feature Drop | 2024.2.2
Kotlin version: 2.0.0
Steps to Reproduce or Code Sample to Reproduce:
1. Use the same PagingSource instance for both a RecyclerView and a LazyColumn.
2. Scroll quickly in RecyclerView → Once new pages are loaded, the scroll continues automatically.
3. Scroll quickly in LazyColumn → Once new pages are loaded, the scroll does not continue.
It appears that LazyColumn only allows scrolling up to the previously available items.
4. Releasing the scroll and then scrolling again makes it possible to continue scrolling.
