QWebEnginePage::iconChanged() not emitted

Take the simplebrowser example.

In TabWidget::createBackgroundTab(), just before the return, add the line

webPage->load(QUrl("https://www.google.com/"));

This will cause new tabs to open google.com by default. However, the tab icon is not updated: it does not show google.com favicon. Instead a default icon is displayed.

Reloading the page, will cause the icon to be displayed.

It seems that when the issue happen QWebEnginePage::iconChanged and QWebEnginePage::iconUrlChanged signals are not emitted.

Note: it is possible to retrieve the icon by calling QWebEngineProfile::requestIconForPageURL once the page has loaded.
