Safe area and status-bar height during the fold animation

We read windowScene.statusBarManager?.statusBarFrame and pin views to the safe area. Mid-fold, the status bar and home-indicator insets change, but several child view controllers do not get viewSafeAreaInsetsDidChange until the animation finishes. Which callbacks are apps expected to use to track safe area continuously through a fold?
