Public bug reported:

If I assign a default value for the selectedIndex, it is expected that
the binding for this value will be kept until the user selects a
different section. Changing the model should not affect that, but it
does, as this example shows:

import QtQuick 2.0
import Ubuntu.Components 1.3

MainView {
    width: 720
    height: 1280

    Page {
        id: myPage
        anchors.fill: parent
        title: "Click the page"
        header: PageHeader {
            id: pageHeader
            title: myPage.title

            extension: Sections {
                id: pageSections

                model: [ "one", "two", "three" ]
                selectedIndex: 1
            }
        }
        MouseArea {
            anchors.fill: parent
            onClicked: pageSections.model = [ "first", "second", "third" ]
        }
    }
}
