NBSP between <img> tag and text doesn't prevent wrapping

import QtQuick

Window {
    width: 640
    height: 480
    visible: true

    Text {
        width: 40
        wrapMode: Text.WordWrap

        readonly property string inlineImage: "<img src='qrc:/(smile).png' width='18' height='18'/>"

        text: inlineImage + '&nbsp;' + 'text'
        textFormat: Text.StyledText

        Rectangle {
            anchors.fill: parent
            color: 'transparent'
            border.width: 1
        }
    }
}
