Hi, after updating to dev12, WithConstraints that's inside of AdapterList keeps getting called which freezes the list during scroll, and then the app crashes Structure:

AdapterList with Modifier.fillMaxSize()
-Box with Modifier.wrapContentHeight() + Modifier.fillMaxWidth()
--ConstraintLayout with Modifier.wrapContentHeight() + Modifier.fillMaxWidth() (I can also see non-stop constraints measure happening, it also gets logged)
---Box with Modifier.fillMaxWidth() + Modifier.aspectRatio(16 / 9f)
----WithConstraints
-----Image (but it also happens with empty WithConstraints block)

Crash:

java.lang.IllegalStateException: Asking for measurement result of unmeasured layout modifier
        at androidx.ui.core.LayoutNodeWrapper.getMeasureResult(LayoutNodeWrapper.kt:63)
        at androidx.ui.core.LayoutNodeWrapper.getMeasuredSize(LayoutNodeWrapper.kt:53)
        at androidx.ui.core.Placeable.getWidth(Placeable.kt:40)

        at androidx.ui.foundation.ListState.composeAndMeasureNextItem-BTEqjtU(AdapterList.kt:237)

I had the same problem with dev11. Maybe it's related to https://issuetracker.google.com/issues/154653504

this could be something separate as well, could you please file a bug? thanks!
