AngularJS v1.6.4: No tag in the file.

I'm given `No tag in the file.` when using this package in my AngularJS controller files. Here's a short preview of what one of my files looks like:

```javascript
/*jslint browser: true, devel: true*/
/*global $ */

window.app.controller('alerts', ['$scope', '$http', function alerts($scope, $http) {
"use strict";
console.log('alerts controller');

$scope.alerts = [];

function foo() {
alert('bar');
}

$http.get('api/dash/getAlerts.php').then(function (response) {

if (!$rootScope.checkResponse(response)) {
return false;
}

$scope.alerts = response.data.alerts;

}, function (response) {
console.error(response);

if (confirm("The server encountered a temporary error and could not complete your request. Do you want to reload to try again?")) {
window.location.reload();
}
});
}]);
```

Reproduce the report in Atom with the provided AngularJS controller file and the package's JavaScript structure-view entry point. First determine why this file produces “No tag in the file”; done means the controller file is parsed without that error and its available symbols appear in the structure view.
