Enter loading substate while waiting for lazy engine to download.

Given

Router.map(function() {
  this.mount('my-engine');
});

and app/templates/my-engine-loading.hbs, the loading substate only enters after the engine has downloaded. Is it possible to enter the loading substate before the engine starts downloading?

@trentmwillis Same here. The loading template shows up until the JavaScript file and CSS file are downloaded.

May be we can have an intermediate transition by triggering _scheduleLoadingEvent here. But _scheduleLoadingEvent requires a routeHandler which will not be available until the engine resources are loaded. Thoughts?
