title: Set popover height
body: <p>I would like to be able to dynamically change the height of my popover window when I click on the toolbar item. The toolbar item and popover already work fine. The code is executed in the popovers javascript.</p>
  
  <p>This page suggests that it can be done but they don't provide any examples:

  <pre><code>You can change the height and width properties of your popover at runtime.
  </code></pre>
  
  <p>Does anyone know how to achieve this?</p>
