ng-strict-di doesn't recognise 'ngInject'

I'm using Rails 4.0 with AngularJS 1.5 and the ng-annotate gem. I've noticed that when I put on the 'ng-strict-di' which forces you to annotate all your direct injections in AngularJS I find that Rails complains about modules which have "ngInject" in place.

eg; Here is my application controller for Angular

ApplicationController = (
  $scope, $timeout,
  hotkeys
  ShortcutService) ->
  "ngInject"
<SNIP>

I have ng-strict-di enabled in my template

<html ng-app='paisApp' ng-strict-di>

When I run my application in dev mode I get an error in the console;

Error: [$injector:strictdi] ApplicationController is not using explicit annotation and cannot be invoked in strict mode

If I manually annotate this then the error goes away, for that file. I have a lot of angularJS files so I don't want to do this for each one.

Update

I'm running my server with NG_FORCE=true like so;

NG_FORCE=true RAILS_ENV=development bundle exec rails s
