Hash permalinks don't work

1. Load http://mozbrick.github.io/blog/#on-x-tag
2. Notice you are not taken to the "On X-Tag" section

Yes, an element with that `id` does exist:

``` html
<h2 id="on-x-tag">
```

But because of the JS fanciness, and because the `id` isn't available on load (likely from the `body[unresolved]`), the anchor doesn't work.
