"CameraPositionState may only be associated with one GoogleMap at a time" when used with Accompanist's HorizontalPager

[nathanjde]

Coming across a crash when trying to embed a GoogleMap inside a HorizontalPager when the CameraPositionState is hoisted outside of the pager

Environment details

• Android Studio Bumblebee 2021.1.1 Patch 3
• Kotlin 1.6.20
• Compose 1.2.0-alpha08
• Accompanist 0.24.7-alpha
• maps-compose 2.1.0

Steps to reproduce

• I've created a demo of the bug here: https://github.com/nathanjde/pagerbug-maps-compose (based off the android-maps-compose demo repo and a single additional commit
• Bug can be reproduced when swiping to the last pager page and back again to the first, or by clicking on any "Details" pager tab and back to the map again

There is code that is supposed to disassociate the map with the CameraPositionState object see: https://github.com/googlemaps/android-maps-compose/blob/main/maps-compose/src/main/java/com/google/maps/android/compose/MapUpdater.kt#L95 so I wonder if the GoogleMap composable isn't properly disposing within a horizontal pager/
