iOS 16.4 Simulator Video

Hello, I develop APPs with Cordova and xCode based on HTML, JavaScript and JS and the iOS WebView. since iOS 16.4 CSS > position:fixed does not work as expected. after scrolling, the fixed element jumps down exactly as far as you scroll. This problem still occurs with iOS 16.5 beta. It occurs on real devices as well as in the simulator! I am sending a video of the problem. I ask for a fix. Thank you Kevin Siml
