WebView does not work with StackView on iOS

WebView does not work on any other screen except the very first one in StackView. This is an issue only on iOS, it works fine on Android or Mac OS X. Attached example demonstrates it. It's not about multiple instances of WebView, you can create as many WebViews as you want on the first screen you push into StackView and it will work on iOS, so something else is broken.
