Using TabRow inside VerticalScroller crashes:

@Composable
fun TextTabs() {
    var state by state { 0 }
    val titles = listOf("TAB 1", "TAB 2", "TAB 3 WITH LOTS OF TEXT")
    VerticalScroller {
        Column {
            TabRow(items = titles, selectedIndex = state) { index, text ->
                Tab(text = { Text(text) }, selected = state == index, onSelected = { state = index })
            }
            Text(
                    modifier = Modifier.gravity(ColumnAlign.Center),
                    text = "Text tab ${state + 1} selected",
                    style = MaterialTheme.typography.body1
            )
        }
    }
}

I just added VerticalScroller to
