Glad that you have succeeded.
Meanwhile, I’ve done some tests and most importantly finally read the
documentation (https://doc.qt.io/qt-5.11/qml-qtwebview-webview.html#url-prop),
so loading documents to WebView through qrc:/ is actually not supported.
However, it does work on Mac OS :) but I guess we should consider this as an
accident happy bonus.
The rest of usecases for qrc:/ work equally fine both on Mac OS and iOS (for
example, setting source for Image).
