Swipe the botomsheet presented on botomsheet

[VGrokhotov]

I found a strange behaviour, that if botomsheet is presented on botomsheet and we swipe the top one down, both will be dismissed. But if we tap on shadow or call dismiss of top one by ourselves, everything will be alright.

I guess the reason is this method of BottomSheetPresentationController:

The tap works with such a way:

Looks like in startInteractiveTransition the presenting controller dismisses, so the both bottomsheets dismisses. Can you please change the behavier to dismiss only presented bottomshet? All my tries failed 😞

I dismiss with swipe only second bottomsheet, both of bottomsheets dismiss

The way I show them:

    func presentAsBottomSheet(_ controller: UIViewController) {
        setPreferredContentSize(controller)
        
        presentBottomSheet(
            viewController: controller,
            configuration: .init(
                cornerRadius: 24,
                pullBarConfiguration: .hidden,
                shadowConfiguration: .init(backgroundColor: .black.withAlphaComponent(0.3), blur: .regular)
            ),
            canBeDismissed: { true },
            dismissCompletion: nil
        )
    }
    
    private func setPreferredContentSize(_ controller: UIViewController) {
        controller.view.layoutIfNeeded()

        let targetSize = CGSize(width: UIScreen.main.bounds.width, height: UIView.layoutFittingExpandedSize.height)
        controller.preferredContentSize = controller.view.systemLayoutSizeFitting(targetSize)
    }
