Scrolling is shaky when LazyColumn elements have varying height

[rpost]

SSCCE (taken from https://github.com/JetBrains/compose-jb/tree/master/tutorials/Desktop_Components#lazy-scrollable-components-with-scrollbar ; changed minimally to introduce variance in LazyColumn element's height):

        title = "Scrollbars",
        state = rememberWindowState(width = 250.dp, height = 400.dp)
    ) {
        LazyScrollable()
    }
}

@Composable
fun LazyScrollable() {
    Box(
        modifier = Modifier.fillMaxSize()
            .background(color = Color(180, 180, 180))
            .padding(10.dp)
    ) {

        val state = rememberLazyListState()

        LazyColumn(Modifier.fillMaxSize().padding(end = 12.dp), state) {
            items(50) { x ->
                TextBox("Item #$x", x)
                Spacer(modifier = Modifier.height(5.dp))
            }
        }
        VerticalScrollbar(
            modifier = Modifier.align(Alignment.CenterEnd).fillMaxHeight(),
            adapter = rememberScrollbarAdapter(
                scrollState = state
            )
        )
    }
}

@Composable
fun TextBox(text: String = "Item", height: Int) {
    Box(
        modifier = Modifier.height((30 + height.mod(2) * 50).dp)
            .fillMaxWidth()
            .background(color = Color(0, 0, 0, 20))
            .padding(start = 10.dp),
        contentAlignment = Alignment.CenterStart
    ) {
        Text(text = text)
    }
}

When I run this and try to scroll slowly down following happens:

Pay close attention to "shaky" content.
