title: Why is youtube iframe causing "Loading failed for the <script> with source"
body: <p>I am using youtube iframe for embeding on my site.  Currently I am in local development, but if I use iframe from youtube, it will give me the error message in console:</p>
  
  <pre><code>Loading failed for the &lt;script&gt; with source “https://static.doubleclick.net/instream/ad_status.js”.
  </code></pre>
  
  <p>I dont have any adblockers on.</p>
  
  <p>After the error, the rest of the page refuses to load and work correctly.  For example, I had javascript loaders at the end of the page, those did not work/load, I have since moved them to the header and now that works.  I am not doing anything magical, just including the iframe youtube has on their site right into the main page.</p>
  
  <p>iframe usage:</p>
  
  <pre><code>&lt;iframe width="560" height="315" src="https://www.youtube.com/embed/#" frameborder="0" gesture="media" allow="encrypted-media" allowfullscreen&gt;&lt;/iframe&gt;
  </code></pre>
