[Compose] ConstraintLayout does not resize to full screen when inside NavHost

[shalva97]

Hi, hpefuly this is right place to report this...

Expectation:
So I have a NavHost with just one destination called "home" and it has a logout button positioned to the top-right corner. Also there is a Loading composable.

When app starts, it will show Loading... and then it should switch to Content(), which displays one button and has a red background.

Actual:
As you can see it only takes space that was first ocupied by Text:

If I use compose version "1.1.1" it works as expected but breaks at version "1.3.0-beta03". Have not tested on other versions...

Here is the code:

package com.shalva97.myapplication

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        setContent {
            JellyList()
        }
    }
}

@Composable
fun JellyList() {
    val navController = rememberNavController()

    NavHost(navController = navController, startDestination = "home") {
        composable("home") {
            Home()
        }
    }
}


@Composable
@Preview
fun Home(navigateToLogin: () -> Unit = { }) {

    var state by remember {
        mutableStateOf("loading")
    }
    val scope = rememberCoroutineScope()

    LaunchedEffect(key1 = 123, block = {
        scope.launch {
            delay(1000)
            state = "content"
        }
    })

    when (state) {
        "loading" -> {
            Text(text = "Loading...")
        }
        "content" -> {
            Content(Modifier.fillMaxSize())
        }
    }
}

@Composable
fun Content(
    modifier: Modifier
) {
    ConstraintLayout(
        modifier = modifier.background(Color.Red)
    ) {
        val (logoutButton, content, bottomNavigation) = createRefs()

        Button(onClick = { }, modifier = Modifier.constrainAs(logoutButton) {
            top.linkTo(parent.top)
            end.linkTo(parent.end)
        }) {
            Text(text = "logout")
        }
    }
