Platform menu icon gets corrupted when changing screen scale factor if the menu item is disabled.

Code sample:

import QtQuick
import QtQuick.Window
import Qt.labs.platform as Platform

Window {
    visible: true

    Platform.Menu {
        id: menu
        Platform.MenuItem {
            text: 'Smile!'
            icon.source: 'qrc:/smile.png'
            enabled: false
        }
    }

    TapHandler {
        acceptedButtons: Qt.RightButton
        onTapped: menu.open()
    }
}
