Found out that the plugin is not working properly and the caused was that it got an uncaught error:
Uncaught Error: [$injector:nomod] Module 'ngLocale' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
Did some digging - this is due to angular-hint-directives having a hack that's since been removed. However, this still appears when installing dependencies manually.
