QML ComboBox breaks dark mode window styling

I am having a really weird issue in the dark mode on windows in connection with a QML ComboBox. The problem I am having is that the dark mode styling "auto detection" breaks as soon I add a ComboBox to the scene.

Here is a small example:

import QtQuick
import QtQuick.Controls

ApplicationWindow {
    width: 800
    height: 600
    visible: true

    menuBar: MenuBar {
        Menu {
            title: qsTr("File")
            Action {
                text: qsTr("&Quit")
                shortcut: StandardKey.Quit
                onTriggered: Qt.quit();
            }
        }
    }

    Rectangle {
        anchors.fill: parent
        color: "darkred"
    }

//    ComboBox {
//        model: ["First", "Second", "Third"]
//    }
}

Everything looks as one would expect. The menu is styled using the correct system setting (dark mode).

Once you uncomment the ComboBox in the example above, the menu styling breaks and resorts back to light mode...

This seems like a bug to me. Can you confirm or am I doing anything wrong?

I am using Qt 6.5.0 on Windows 11 with MinGW 11.2.0.
