googletag defineslot with shadow dom
<p>I would like to add double click ads tags to an element using :</p>

<blockquote>
  <p>googletag.defineSlot(adUnitPath, size, opt_div)    Constructs an ad slot
  with a given ad unit path and size and associates it with the ID of a
  div element on the page that will contain the ad.</p>
</blockquote>

<p>like this :</p>

<pre><code>googletag.defineSlot('myslot', [728, 90], 'ad-container')
</code></pre>

<p>the ad-container div is in a Polymer webcomponent and the application is set with shadow dom enable. The div is not found by googletag api. The publisher console output :</p>

<blockquote>
  <p>Slot 'myslot' does not have a container div with id: 'ad-container'.</p>
</blockquote>

<p>if app is switch to shady dom, it works.</p>

<p>Is there a way to get googletag with shadow dom ?</p>
