* 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.
