When using TalkBack, markers inside the BottomSheetScaffold content steal focus even when the sheet content is covering the map.

Environment details

• com.google.maps.android:maps-compose:5.0.3
• Any Android API

Steps to reproduce

1. Setup BottomSheetScaffold
2. Add a map with markers as content
3. Add any composable as sheetContent
4. Enable talkback
5. Markers can be focused event when the sheetContent is covering the map

Code example

@OptIn(ExperimentalMaterial3Api::class)
@Composable
fun ScaffoldMap() {
    BottomSheetScaffold(
        sheetContent = { SheetContent() }
    ) { padding ->
        MapContent(padding)
    }
}

@Composable
fun MapContent(padding: PaddingValues) {
    val singapore = LatLng(1.35, 103.87)
    val cameraPositionState = rememberCameraPositionState {
        position = CameraPosition.fromLatLngZoom(singapore, 12f)
    }
    GoogleMap(
        modifier = Modifier.fillMaxSize().padding(padding),
        cameraPositionState = cameraPositionState
    ) {
        for (i in 1..50) {
            Marker(
                state = rememberMarkerState(position = LatLng(1.35 + i * 0.001, 103.87 + i * 0.001)),
                title = "Marker $i"
            )
        }
    }
}

@Composable
fun SheetContent() {
    LazyColumn {
        items(100) { index ->
            Button(
                onClick = { },
                modifier = Modifier
                    .fillMaxWidth()
                    .padding(8.dp)
            ) {
                Text(text = "Button $index")
            }
        }
    }
}

Hi @MaCls98 ,

This does seem to be an specific issue when using a BottomSheetScaffold, not something exclusively related to android-maps-compose. You can verify that by changing the background UI.

What about setting the visibility of the components manually depending on whether the sheet is visible or not?

Also, support (and lack of it) was added on this PR, maybe you can deactivate the map if the sheet is visible.

Hello @kikoso

I tried to update mergeDescendants dynamically, but the map takes the first value that is passed to the composable, when mergeDescendants is false, the focus works as expected, but the map isn't accessible with talkback

Also, I tried to replicate the same behavior, replacing the map with buttons, and in that case, the focus worked as expected.
