Built-in Group (use idMso) can't change the label? RRS feed

  • Question

  • I add a built-in Group into the custom ribbon, using "idMso"

            <group idMso="GroupStyles" label="testGroup1">

    but the label can't change, why?

    the gallery、button using "idMso" can change the label, why group can't? Is it a bug?

    <?xml version="1.0" encoding="UTF-8"?>
    <customUI xmlns="" onLoad="Ribbon_Load">
          <tab id="myTab" label="myTab">
            <group idMso="GroupStyles" label="testGroup1">
            <group id="testGroup" label="testGroup2">
              <gallery idMso="PasteGallery" label="testPaste"></gallery>
              <button idMso="Copy" label="testCopy"/>
