Component used: Navigation
Version used: 2.7.1
Devices/Android versions reproduced on: Pixel 7

Using the navigation compose in the previous version I was able to immediately navigate away from the landing screen, if the user is logged in, with a nice crossfade animation playing between my landing screen and main screen. See: it-was-working-in-2.7.0-beta02.mp4

Upon updating the experience has gotten worse: when navigating away from the landing screen (while it's enter animation hasn't finished yet), a weird inflating animation is playing. See: expanding-bug.mp4

Since these are only cross fade animations the size of the container should never change. Why does the size of the container animating for a simple crossfade animation?

Expected behavior:
Since the size of the initial screen doesn't change during it's enter transition, I would expect the second screen to only play a fade in animation without the weird clipping/size changing that's happening at the moment.

Code to reproduce: (see also NavHostBugReport.zip)
```
NavHostBugReportTheme {                                                  
    // A surface container using the 'background' color from the theme    
    Surface(                                                              
        modifier = Modifier.fillMaxSize(),                                
        color = MaterialTheme.colorScheme.background                      
    ) {                                                                  
        val navController = rememberNavController()                      
        NavHost(navController = navController, "@landing") {              
            navigation("landing", "@landing") {                            
                composable("landing") {                                    
                    Box(modifier = Modifier                              
                        .fillMaxSize()                                    
                        .background(Color.Red))                          
                    LaunchedEffect(key1 = Unit) {                          
                        navController.navigate("main")                    
                    }                                                    
                }                                                        
            }                                                            
            navigation("main", "@main") {                                  
                composable("main") {                                      
                    Box(modifier = Modifier                              
                        .fillMaxSize()                                    
                        .background(Color.Blue))                          
                }                                                        
            }                                                            
        }                                                                
    }                                                                    
}                                                                        
```

If this is a bug in the library, we would appreciate if you could attach:
- Sample project to trigger the issue. (attached: NavHostBugReport.zip)
- A screenrecord or screenshots showing the issue (if UI related).
