title: Script tag in Aurelia view is not executed
body: <p>I'm adding a simple script block to a simple aurelia view:</p>
  
  <pre><code>&lt;template&gt;
      &lt;script type="text/javascript"&gt;
      alert('Hello!');
      &lt;/script&gt;
  &lt;/template&gt;
  </code></pre>
  
  <p>The script is never run, even though the view is rendered correctly and I can see that the script block does appear in the DOM. </p>
  
  <p>I have also tried dynamically inserting a script block via the viewModel and also tried with:</p>
  
  <pre><code> &lt;script type="text/javascript" src="http://blah"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>I understand it's not best practice to do this, but I'm trying to integrate a third party widget that will then render an iframe. The alert shown above is just a simple way of the verifying the issue that I'm seeing.</p>
  
  <p>The real life scenario is as follows:</p>
  
  <ul>
  <li>I make an api call to a third party from my view model.</li>
  <li><p>The following is returned:</p>
  
  <p><code>&lt;script type='text/javascript' language='JavaScript'</code> src='<a href="https://secure.na1.echosign.com/public/embeddedWidget">https://secure.na1.echosign.com/public/embeddedWidget</a>? ` wid=CBFCIBAA3AAABLblqZhBU33GaMRZ2lMelHKzti7RkanxMP5v- uW_f8CEiKoopNNofJWyXhmE56Su3HTbY*&amp;token=CBNCKBAAHBCAABAARNiZ7Yba0h7dnLaQRBAdTdH9UrJZKryP' /></p></li>
  </ul>
  
  <p>I need to append this to the DOM and have it execute. I am working around this issue by calling the above url via fetch and then I exec the response, but it seems like a tedious/hacky way of doing it. </p>
