After the Activity recreated, progress is fixed at 1.0

[Gargantua7]

After the Activity recreated (eg. daynight theme changed, screen orientation change), even if content scrolling occurs, the value of CollapsingToolbarState.progress will not change and is fixed at 1.0.

demo code:

val state = rememberCollapsingToolbarState()
CollapsingToolbarScaffold(
    state = rememberCollapsingToolbarScaffoldState(state),
    scrollStrategy = ScrollStrategy.ExitUntilCollapsed,
    modifier = Modifier.fillMaxSize(),
    toolbar = {
        Spacer(
            modifier = Modifier.fillMaxWidth()
                .height(160.dp)
                .background(Color.Yellow)
        )
        Spacer(modifier = Modifier.height(10.dp).pin())
    }
) {
    LazyColumn(modifier = Modifier.fillMaxSize()) {
        item { Text(text = "${state.progress}") }
        items(1000) {
            Text(it.toString())
        }
    }
}
