Qt::WA_Mapped maps (sic) to windowHandle()->isExposed(), and we set/update
it in QWidgetWindow::handleExposeEvent(). Setting it directly in show_sys
shortcuts QPA and assumes showing a window is synchronous on all platforms,
resulting in trying to flush the widget backingstore when the window was
not exposed yet (due to discardSyncRequest starting to return false).
