QWebEngineProfile: Using custom persistent storage path still produces empty folder at default storage path location

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);

    QWebEngineProfile p("MyBrowser");
    p.setHttpCacheType(QWebEngineProfile::DiskHttpCache);
    p.setCachePath("D:/MyBrowser");
    p.setPersistentStoragePath("D:/MyBrowser");

    QWebEngineView view(&p);
    view.setUrl(QUrl{"chrome://qt"});
    view.show();

    app.exec();
}
