Jetpack Compose release version: 1.0.0-alpha10

Steps to Reproduce:

@Preview
@Composable
fun Test() {
    val density = AmbientDensity.current
    Box(
        modifier = Modifier
            .onSizeChanged { println(it) }
            .padding(with(density) { 50.toDp() })
            .size(with(density) { 50.toDp() })
            .background(Color.Red)
    )
}

Expected printout: 150 x 150
Actual printout: 50 x 50

On the other hand if I replace onSizeChanged with layout it prints expected result.

modifier = Modifier
    .layout { measurable, constraints ->
        val placeable = measurable.measure(constraints)
        println("${placeable.width} x ${placeable.height}")
        layout(placeable.width, placeable.height) {
            placeable.place(0, 0)
        }
    }
    .padding(with(density) { 50.toDp() })
    .size(with(density) { 50.toDp() })
    .background(Color.Red)
