WebView does not work with StackView

This might be a regression, cause I reported similar bug long time ago in 5.6.0 and it was fixed in 5.6.3 (QTBUG-54128), but at this time it isn't only on iOS, but on Android as well (tested with Qt 5.7.0 and 5.8.0 beta).
The bug is that WebView does not work on any other screen in StackView except the very first one. Very easy reproducible, see the attached example. In the application I'm working on WebView actually appears, but very highly scaled and overlapping all the QML content, and in the attached example it isn't visible, so obviously something is wrong with geometry. It gets fixed once device orientation is changed from portrait to landscape or vice versa.
