   * @param aSheet the sheet that was loaded. Guaranteed to always be
   *        non-null, even if aStatus indicates failure.
   * @param aWasAlternate whether the sheet was an alternate.  This will always
   *        match the value LoadStyleLink or LoadInlineStyle returned in
   *        aIsAlternate if one of those methods were used to load the sheet,
   *        and will always be false otherwise.
   * @param aStatus is a success code if the sheet loaded successfully and a
   *        failure code otherwise.  Note that successful load of aSheet
   *        doesn't indicate anything about whether the data actually parsed
   *        as CSS, and doesn't indicate anything about the status of any child
   *        sheets of aSheet.
