What is the cause for this crash? This happens when I click on a LazyColumn item to navigate to a Composable screen destination, it happens randomly..

```java.util.NoSuchElementException: Key LayoutNode@8c58436 children: 0 measurePolicy: androidx.compose.ui.node.LayoutNode$Companion$ErrorMeasurePolicy$1@2c7a10a is missing in the map.

Hah! I just upgraded to beta08 today and had the similar looking bug, but in `Swipeable`, and the key was  a simple 'Float' value. Otherwise it looked the same. Also happened randomly.

Not sure if this is a coincidence.

Filed a bug to investigate <https://issuetracker.google.com/issues/190723041>

<@UJN92AYA0> Hi! I have a similar looking crash randomly reproducing in `Swipeable`, after leaving and entering an app on Android 11 (seemingly). This is `beta09`.

Can this be related somehow?

No, this one is different. Please file a bug if you don’t mind
