maybe add a comment that this divs styling is changed by the root element.

__idea:__
What if we remove the `ng-if` and then use css to hide the DOM unless the item is a pull (as determined by a class on the issue).  The idea came from how squarespace did their styling.  They show everything and then let the designer decide how to display it.

```html
<div ng-controller="IssueCtrl as issueCtrl"
     class="card" ng-class="[issueCtrl.getBuildStatus(), issueCtrl.isPull()]"
...
```
