      Resulted from "Introduce Windows 11 styled ComboBox in QWindows11Style" 9da8d67b3bca1d40ae221a9c6be218fe57759724 https://codereview.qt-project.org/c/qt/qtbase/+/481184 where it now always destroys the view if style changes:

      void QComboBox::changeEvent(QEvent *e)
{
    Q_D(QComboBox);
    switch (e->type()) {
    case QEvent::StyleChange:
        if (d->container) {
// If on Windows, force recreation of ComboBox container, since
// windows11 style depends on WA_TranslucentBackground
#ifdef Q_OS_WIN
            auto delegate = itemDelegate();
            d->container->deleteLater();
