30 * StyleSheetLoaded is called after aSheet is marked complete and before any
31 * load events associated with aSheet are fired.
32 * @param aSheet the sheet that was loaded. Guaranteed to always be
33 * non-null, even if aStatus indicates failure.
34 * @param aWasDeferred whether the sheet load was deferred, due to it being an
35 * alternate sheet, or having a non-matching media list.
36 * @param aStatus is a success code if the sheet loaded successfully and a
37 * failure code otherwise. Note that successful load of aSheet
38 * doesn't indicate anything about whether the data actually parsed
39 * as CSS, and doesn't indicate anything about the status of any child
