iOS. Animation crashes with OOM inside bottom sheet

[logutenko]

When playing an animation inside bottom sheet, a large amount of memory is allocated. This causes an application to crash with OOM error.

Affected platforms

• iOS

Versions

• Libraries:
  • Compose Multiplatform: 1.6.10
• Kotlin: 2.0.0
• OS: 17.1.1
• OS architecture: arm64
• Device: iPhone 15 Pro

To Reproduce Steps to reproduce the behavior:

1. In the example graphics-2d replace Scaffold with ModalBottomSheet:

   @OptIn(ExperimentalMaterial3Api::class)
   @Composable
   fun Graphics2D(requestWindowSize: ((width: Dp, height: Dp) -> Unit) = EMPTY_WINDOW_RESIZER) {
   val exampleState: MutableState<Example?> = remember { mutableStateOf(null) }
   val example = exampleState.value
   
   MaterialTheme(
       colorScheme = if (isSystemInDarkTheme()) darkColorScheme() else lightColorScheme()
   ) {
       ModalBottomSheet(onDismissRequest = {}) {
           if (example == null) {
               LazyColumn(Modifier.padding(horizontal = 16.dp)) {
                   items(examples) {
                       Button(onClick = {
                           exampleState.value = it
                       }) {
                           Text(it.name)
                       }
                   }
               }
           } else {
               example.content { w, h ->
                   requestWindowSize(w, h + TOP_APP_BAR_HEIGHT)
               }
           }
       }
   }
   }

2. Run an app and click on RotatingWords button
3. OS terminates app

According to the profiler, memory consumption is over 3 GiB
