    Description

      As discovered in QTBUG-74559 and QTBUG-69289 QWidget does not handle surfaces created or destroyed under its feet, e.g. not initiated by QWidget::create or QWidget::destroy. The winId and created-attribute, among others, gets out of sync.

      We should handle QPlatformSurfaceEvent by running the relevant parts of the QWidget::create/destroy logic.
