google map zoom event: Ignored attempt to cancel a touchend event with cancelable=false
<p>I'm using google map in my ionic 2 app, and I want my markers to display/disappear depending on the map's zoom level. So I added the following line in the function "ionViewDidEnter":</p>

<pre><code>    this.map.addListener('idle', this.adjustMarkerVisibility);
</code></pre>

<p>However, when I zoom the map (or even just scrolling it), I get a warning </p>

<blockquote>
  <p>"Ignored attempt to cancel a touchend event with cancelable=false, for example because scrolling is in progress and cannot be interrupted."  </p>
</blockquote>

<p>and this.adjustMarkerVisibility() is never called. I've searched the error for a while but nothing relating with google map has come up. Anyone with any suggestions? Thanks!</p>
