Kendo MVC TabStrip Tabs will not open

Question

My Kendo MVC TabStrip Tabs will not open. Only where selected is true will it show tab content. In this example, the Resolution and Hist tabs are not opening. No console errors.

  <div class="col col-lg-12">
    <section class="well" id="">
        <h1>Workflow Details</h1>
