Exit until collapsed scrollStrategy behaves wrong

[Veeksi]

Hey,

I have an issue with ExitUntilCollapsed scroll strategy. Somehow, the collapsing toolbar makes weird jump to top when navigating to next page and back. The issue can be seen in this video: https://streamable.com/j13xjn

However, if I change the scroll strategy to something else, then there is no jump after navigating back. The issue disappears also if I don't use collapsing toolbar at all.

val toolbarState = rememberCollapsingToolbarScaffoldState()

Surface {
    CollapsingToolbarScaffold(
        modifier = Modifier.fillMaxSize(),
        state = toolbarState,
        scrollStrategy = ScrollStrategy.ExitUntilCollapsed,
        enabled = true,
        toolbar = {
            SmallTopAppBar(
                modifier =
                    Modifier.padding(top = 38.dp).graphicsLayer {
                        alpha = 1 - state.toolbarState.progress
                    },
                title = { Text(title, overflow = TextOverflow.Ellipsis, maxLines = 1) },
                navigationIcon = {
                    IconButton(onClick = { navigateBack() }) {
                        Icon(
                            Icons.Default.ArrowBack,
                            contentDescription = "backButton",
                        )
                    }
                },
            )
            Box(
                modifier =
                    Modifier.fillMaxSize().padding(bottom = 8.dp).graphicsLayer {
                        alpha = state.toolbarState.progress
                    }
            ) { Box(modifier = Modifier.height(200.dp).background(Color.Red)) }
        },
    ) {
        Scaffold { LazyColumn(modifier = Modifier.fillMaxWidth().padding(it)) { Content() } }
    }
}
