+// The loadstart and error event firing tasks are queued in the synchronous
+// section of the resource selection algorithm, so no tasks can come between
+// them. Calling load() in the loadstart event handler removes the queued error
+// event task at very latest opportunity, failing any implementation that fires
+// the events in the same task.
