  @param {CKEDITOR.dom.element} element
  @param {Boolean} fullMatch
  @param {CKEDITOR.editor} editor The editor instance. Required argument since
  CKEditor 4.4. The style system will work without it, but it is highly
  recommended to provide it for integration with all features. Read more about
  the signature change in the {@link CKEDITOR.style} documentation.
  @returns {Boolean}
