Feel free to give a shot fixing it. That said -- this whole API is part of SwiftUI now (and better in some ways), so I would consider this "unmaintained".

Thank you for prompt reply, I came up with a workaround by listening the UIApplication.willEnterForegroundNotification event to reset the configuration the inside HostingController's lifecycle, this should work.
