Jetpack Compose release version: 1.1.1 & 1.2.0-alpha04

With some animation types, including AnimatedVisibility default ones, the view doesn't appear at all.

var flag by remember { mutableStateOf(true) }
Scaffold(
    floatingActionButton = {
        AnimatedVisibility(visible = flag)
        {
            FloatingActionButton({}) {
                Icon(Icons.Default.ArrowBack, null)
            }
        }
    },
) {
    Switch(flag, { flag = it })
}

ScaleIn/out works fine.

If I put AnimatedVisibility in a Box(Modifier.size(FabSize)), it works almost fine, expect the shadow - it's being clipped during animation until the final frame.
