// Reads "One" -> "Two" -> "Three"
Row(modifier = Modifier.semantics(mergeDescendants = false) { }) {
    Text("One")
    Column {
        Text("Two")
        Text("Three")
    }
}

// Reads "One Two Three"
Row(modifier = Modifier.semantics(mergeDescendants = true) { }) {
    Text("One")
    Column {
        Text("Two")
        Text("Three")
    }
}

// Reads "One" -> "Two Three"

    Text("One")
    Column(modifier = Modifier.semantics(mergeDescendants = true) { }) {
        Text("Two")
        Text("Three")
    }
}

// Reads "Custom Description One Two Three"
Row(modifier = Modifier.semantics(mergeDescendants = true) {
    contentDescription = "Custom Description"
}) {
    Text("One")
    Column {
        Text("Two")

// Reads "Custom Description"

}) {
    Text("One")
    Column {
        Text("Two")
        Text("Three")
