Bug description:

The accordion custom template example listed at https://angular-ui.github.io/bootstrap/#/accordion is applying a duplicate panel and panel-default style causing a thicker than intended box shadow.

    <div class="panel panel-default">
      <div class="panel-heading">
        <h4 class="panel-title" style="color:#fa39c3">
          <a href="" tabindex="0" class="accordion-toggle" ng-click="toggleOpen()" uib-accordion-transclude="heading">
            <span uib-accordion-header="" ng-class="{'text-muted': isDisabled}" class="ng-binding">
              Custom template
            </span>
          </a>
        </h4>
      </div>
      <div class="panel-collapse collapse" uib-collapse="!isOpen" aria-expanded="false" aria-hidden="true" style="height: 0px;">
        <div class="panel-body" style="text-align: right" ng-transclude=""><span class="ng-scope">
      Hello
    </span></div>
      </div>
    </div>
  </div>
