Buttons with the class button-full do not render properly when included in an ion-footer-bar. For instance:
<ion-footer-bar>
<div class="buttons">
<button class="button button-full">Button 1</button>
</div>
<h1 class="title">Title</h1>
<div class="buttons" ng-click="doSomething()">
<button class="button">Button 2</button>
</div>
</ion-footer-bar>
