Non-breaking space does not work with StyledText

import QtQuick 2.3
import QtQuick.Layouts 1.1

ColumnLayout {
    Text { // the spaces will be invisible
        Layout.fillWidth: true
        text: "This Text should not wrap but look as if there were spacs"
        textFormat: Text.StyledText
        wrapMode: Text.WordWrap
    }

    Text { // the spaces are rendered properly and won't wrap
        Layout.fillWidth: true
        text: "This Text should not wrap but look as if there were spaces"
        textFormat: Text.RichText
        wrapMode: Text.WordWrap
    }
}
