// 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.
