If I create an element with an AngularJS tag and use an inline if statement inside of that tag, the formatting is broken on the "else" choice. 
Example:
<i ng-class="true ? 'icon-up-arrow' : 'icon-down-arrow'"></i>
Results after applying formatting:
<i ng-class="true ? 'icon-up-arrow' : 'icon - down - arrow'"></i>

The HTML editor views 'icon-up-arrow' correctly as a string, but it views 'icon-down-arrow' as Javascript, and runs it through the binary operator format style and spaces are inserted around the - signs. A workaround of some sort is to go into Javascript formatting and turn off spaces for binary operators (not ideal if you are working with both HTML & JS).
