emberjs.com/api does not return fastboot-rendered page #427
Description
When you visit a specific API doc URL on emberjs.com, like https://emberjs.com/api/ember/2.18/classes/Engine, the html page is not populated as you would expect fastboot to do. What we would expect is the site to initially return the completely hydrated page, but what happens is only the initial bare index html is returned, and then hydrated by javascript, as a non-fastboot app would be. This raises some potential problems for seo/web crawlers, and negates the benefit of fastboot.
