Jetpack Compose release version: alpha12 Android Studio Build: Android Studio Arctic Fox | 2020.3.1 Canary 7 Build #AI-203.7148.57.2031.7136282

Steps to Reproduce:

1. First box inside a column is kind of a top bar. I expect it to stay on the screen during editing

Column(
        modifier = Modifier
            .fillMaxSize()
    ) {
        Box(
            modifier = Modifier
                .fillMaxWidth()
                .height(50.dp)
                .background(Color.Red.toColor())
        ) 
        Column(
            modifier = Modifier
                .verticalScroll(rememberScrollState())
                .fillMaxSize()
        ) {
            (0..100).forEach {
                BasicTextField(value = it.toString(), onValueChange = { /*TODO*/ })
            }
        }
    }

2. When one of the top text fields gets selected, everything is fine, even if later you select an other one while keyboard is on screen
3. If you select one of the bottom ones, "top bar" disappears from the screen as if it was inside scrollable column.
4. Same happens with a LazyColumn
