Jetpack Compose version: 1.6.0-alpha05
Jetpack Compose component used: TooltipBox
Android Studio Build: Android Studio Iguana | 2023.2.1 Canary 2 (AGP 8.1.1)
Kotlin version: 1.9.10

After updating to compose 1.6.0-alpha05, my app was crashing after pressing the home button to leave the app. After some testing, I think the app crashes when TooltipBox is used.

I've attached a small app that I've been using to test the bug on different devices, but any app that uses TooltipBox should have the issue.

Steps to reproduce:

Open demo app
Use the Switch to display the Icon + Tooltip composable
Click the Home button

The app should crash with a RuntimeException. If we hide the Icon + Tooltip before clicking Home, the app won't crash.

I've tested the app on a device running SDK 30 and on three emulator images running 26, 29 and 33.

I hope this is not a problem with my TooltipBox implementation. I've used the same composable from TooltipSamples to avoid mistakes.
