Comment 5 for bug 1599771

I suspect that oxide::qquick::ContentsView::HasFocus also needs to verify that item_ == item_->window()->activeFocusItem() (http://doc.qt.io/qt-5/qquickwindow.html#activeFocusItem-prop). It looks like this is cleared before dispatching QQuickItem::focusOutEvent(), whereas QQuickItemPrivate::activeFocus isn't.
