Improper positioning when moving between screens with different densities

[sproctor]

Reproducer here: https://github.com/sproctor/ComposeBug/tree/dpi-change-bug

The text should stay to the right of the gray box.

The measurer does mention that DPI can change. I think this would cause a configuration change on Android and recreate the activity, so it wouldn't be a problem. On desktop, this doesn't happen.

My first intuition is that these lines need to be keyed to the density:

constraintlayout-compose-multiplatform/compose/src/commonMain/kotlin/androidx/constraintlayout/compose/ConstraintLayout.kt

Line 420 in 07c8cb3

val measurer = remember { Measurer(density) }

constraintlayout-compose-multiplatform/compose/src/commonMain/kotlin/androidx/constraintlayout/compose/ConstraintLayout.kt

Line 802 in 07c8cb3

val measurer = remember { Measurer(density) }
