linking to leaf page causes error

[nlfurniss]

Navigating to https://ember-scroll-modifiers.jhawk.co/ and then clicking the navigation links on the left works just fine, but going directly to https://ember-scroll-modifiers.jhawk.co/modifiers/did-intersect causes this error:

Uncaught (in promise) Error: Could not find module `innertext` imported from `field-guide/services/head-data`
