title: Added non-passive event listener to a scroll-blocking 'touchstart' event
body: <p>Suddenly today, out of nowhere, I started getting this one on every page on our website</p>
  <pre><code>Added non-passive event listener to a scroll-blocking 'touchstart' event.
  Consider marking event handler as 'passive' to make the page more responsive
  </code></pre>
  <p>And its not just once or twice.. its like thousands of them....</p>

  <p>They are running amok.</p>
  <p>The only way to stop the flood of violations is to comment out this line</p>
  <pre><code>  &lt;script src=&quot;https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.4/jquery.min.js&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt;
  </code></pre>
  <p>I read the other posts on what this violation means, but I really cannot see that I did anything different between two hours ago and now (I did a full rollback just to see if it helped)</p>
  <p>It's almost like someone put a bug into jquery.min.js but I seriously doubt that, because then everyone would get it.</p>
  <p>Any ideas?  I tried debugging everything I could and I still have no idea what causes this?!?</p>
  <p><strong>UPDATE</strong></p>
  <p>I replaced all <code>&lt;button&gt;&lt;md-tooltip&gt;text&lt;/md-tooltip&gt;&lt;/button&gt;</code> with <code>&lt;button data-toggle=&quot;tooltip&quot; title=&quot;text&quot;&gt;&lt;/button&gt;</code> This removed 99% of all the violations.</p>
