Jetpack Compose version: androidx.compose.foundation:foundation:1.6.0-alpha02

Jetpack Compose component(s) used: AnchoredDraggableState

Android Studio Build: Giraffe

Kotlin version: 1.8.10

Steps to Reproduce or Code Sample to Reproduce:

The progress property in AnchoredDraggable state does not update when re-anchoring; it only updates during user interaction.

    LaunchedEffect(state.progress) {
        println("progress: ${state.progress}")
    }

In the snippet above, progress will only update when dragging a widget with the modifier applied. Once draging stops and reanchoring begins to the nearest anchor, the progress value does not update until the Composable has snapped back and settled.

This makes it impossible to animate smoothly as the progress snaps to the the end value instead of being updated continuously.
