    Handle LO's recently-corrected exposure of text attributes for spellcheck
    
    Note: The LO fix has only just been committed and is not yet available
    in shipping versions of LO. In addition, in recent, earlier versions of
    LO, a broken LO accessibility tree made it impossible for Orca to find
    the spellcheck dialog. If your version of LO does not have fixes for both
    of these issues, this change to Orca will not work.
