Not possible to close a modal ComboBox popup by clicking on the ComboBox

Desktops typically have modal popups for combo boxes. Currently there is no modal flag for ComboBox exposed, which means that when a ComboBox is open and user wishes to dismiss it by clicking somewhere else on the window, it actually registers that as a click. So it could lead to unintended action being taken.

One could almost do it with popup.modal: true already though. Only issue is that combobox cannot be closed by clicking the combobox button itself while the popup is open.

import QtQuick
import QtQuick.Controls

ApplicationWindow {
    id: window
    width: 600
    height: 400
    visible: true

    ComboBox {
        model: 10
        popup.modal: true
        popup.y: height
    }

    Switch {
        x: 200
        y: 100
        text: "I shouldn't respond to clicks when the popup is open"
    }
}
