<h2>Pre-Rendered Dialog</h2>
<p>
This is a pre-rendered dialog, which means that <code>$mdDialog</code> doesn't compile its
template on each opening.
<br/><br/>
The Dialog Element is a static element in the DOM, which is just visually hidden.<br/>
Once the dialog opens, we just fetch the element from the DOM into our dialog and upon close
we restore the element back into its old DOM position.
