Windows insets ignored if isModal = true

[sergionettl]

Please complete the following information:

• Library Version: v0.1.5
• Affected Device(s): all

Describe the Bug: (when isModal is true) Even if you set the windowInsets to PaddingValues(0.dp) and containSystemBars = true, the statusBar padding is applied.

Expected Behavior: window insets are respected. E.g. If no systemBar window insets are added FullyExpanded bottom sheet should overlap top of the screen (edge to edge behaviour)

Note: The origin of the problem seems to come from: FlexibleBottomSheet.kt L292

modifier = if (sheetState.isModal) {
            Modifier
              .fillMaxWidth()
              .sheetPaddings(sheetState)
          } else {
            Modifier
              .fillMaxWidth()
          },

public fun Modifier.sheetPaddings(sheetState: FlexibleSheetState): Modifier = composed {
  val systemBarsPadding = WindowInsets.systemBars.asPaddingValues()
  val paddings =
    systemBarsPadding.calculateBottomPadding() + systemBarsPadding.calculateTopPadding()
  val availableHeight = screenHeight() * (1 - sheetState.flexibleSheetSize.fullyExpanded)
  val padding = availableHeight - paddings

  if (sheetState.currentValue == FlexibleSheetValue.FullyExpanded && padding.toPx() > 0) {
    Modifier.padding(bottom = availableHeight - paddings)
  } else {
    this
  }
}
