// Qt bug workaround: QWidget::render() for an arbitrary widget calls
// sendPendingMoveAndResizeEvents(true, true) for the whole window,
// which does something like:
//
// setAttribute(Qt::WA_UpdatesDisabled);
// sendEvent(QResizeEvent);
// setAttribute(Qt::WA_UpdatesDisabled, false);
//
// So if we create TabbedSection widget in HistoryWidget::resizeEvent()
// it will get an enabled Qt::WA_UpdatesDisabled from its parent and it
// will never be rendered, because no one will ever remove that attribute.
//
// So we force HistoryWidget::resizeEvent() here, without WA_UpdatesDisabled.
