LazyColumn's scroll position resets on system-initiated process death

Problem: when I perform this sequence of events the LazyColumn's scroll position resets:

1. From homepage, swipe up
2. background/foreground app with "Don't Keep Activities" option enabled

or:

1. From a community page, swipe up
2. background/foreground app with "Don't Keep Activities" option enabled

Possible solution:

save the posts list using SavedStateHandle and declare the postListState using rememberLazyListState() in a Composable instead of using a ViewModel

declare the postListState using rememberLazyListState() in a Composable instead of using a ViewModel

Not possible, it used to be like this. But if you switch between home and any other tab (inbox/profile...). You will lose the position.

Thats why HomeViewmodel doesn't follow the lifecycle of HomeScreen and why it keeps the state.
