I have the following compose function:

@Preview
@Composable
fun Test(){
    Column(modifier = Modifier.fillMaxSize()) {
        Text(
            text = "hello1",
            lineHeight = TextUnit(50f, TextUnitType.Sp)
        )
        Text(
            text = "hello2",
            lineHeight = TextUnit(500f, TextUnitType.Sp)
        )
    }

}

I expect to see 2 texts with different line height, but for some reason none of them have any height changes:

Why?
