java.lang.IllegalStateException when toggling switches in nested scrollViews

[Lefix2]

Describe the bug When using switches (and perhaps other toggle components) in nested scrollViews (one vertical and one horizontal), if we interact with a conditionnal composable, the app crash in some conditions.

Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: LayoutCoordinates androidx.compose.ui.node.ModifiedLayoutNode@28f86b4b is not attached!

Affected platforms

• Desktop

Versions

• Kotlin version: jvm-1.7.20
• Compose Multiplatform version: 1.2.2
• OS version(s): Ubuntu 22.04.2 LTS
• OS architecture: x64
• JDK: 17

To Reproduce

var s1 by remember { mutableStateOf(true) }
var s2 by remember { mutableStateOf(true) }
var s3 by remember { mutableStateOf(true) }
Column( modifier = Modifier.verticalScroll(rememberScrollState())) {
    Switch( s1, { s1 = it })
    Switch( s2, { s2 = it })
    if (s2) {
        Row(modifier = Modifier.horizontalScroll(rememberScrollState())) {            
            Switch(s3, { s3 = it })
        }
    }
}

Expected behavior

• toggle s3 at least once then toggle s2, the app will crash
• toggle s3, then s1, then s2, the app will not crash
• toggle s3, resize window and scroll up to let s3 out of view, toggle sé, the app will not crash

I tried the same code with Compose 1.4.0 and Kotlin 1.8.20, and it worked fine. Can you please try a newer version of Compose?

[Lefix2]

I confirm, with recent version bug is not present! Thanks for the feedback
