Weird sheet offsetting when dragging using `isModal = false`

[RoosDaniel]

Please complete the following information:

• Library Version: 0.1.5
• Affected Device(s): Google Pixel 8 running android 15, also appears in emulator

See video. When dragging the sheet with isModal = false, it offsets down and then goes back to expected position after it's done animating.

This is the code:

val sheetState = rememberFlexibleBottomSheetState(
        flexibleSheetSize = FlexibleSheetSize(
            fullyExpanded = 1.0f,
            slightlyExpanded = 0.10f,
        ),
        isModal = false,
        skipHiddenState = true,
        skipSlightlyExpanded = false,
        skipIntermediatelyExpanded = true, // doesn't seem to make a difference
        containSystemBars = true,  // doesn't seem to make a difference
    )

var currentSheetStateTarget by remember {
    mutableStateOf(FlexibleSheetValue.SlightlyExpanded)
}

FlexibleBottomSheet(
        onDismissRequest = { },
        sheetState = sheetState,
        onTargetChanges = { currentSheetStateTarget = it }
    ) {
        Column(
            modifier = Modifier.fillMaxWidth(),
            horizontalAlignment = Alignment.CenterHorizontally,
        ) {}
    }

After some more investigation, it seems like this appears only for when setting fullyExpanded = 1.0f. Using a lower value fixes it.

I've got the same problem, maybe it's linked to Android 15. Even with 0.9, You can also see that my BottomNavigation is back in front for a while. https://github.com/user-attachments/assets/98e9c0c9-73e1-4f10-ba75-d4e7664d3875

I understood the problem, it is linked to the popup and to windowsmanager. I found another project which proposes another approach and by combining their solution it works.
