title: Input range slider not working on iOS Safari when clicking on track
body: <p>I have a pretty straight-forward range input slider.  It works pretty well on all browsers except on iOS Safari.  </p>
  
  <p>The main problem I have is when I click on the slider track, it doesn't move the slider.  It merely highlights the slider.  It works fine when dragging the thumb.  Any ideas on how to fix this?</p>
  
  <pre><code>&lt;div class="slider-wrap"&gt;
      &lt;div id="subtractBtn"&gt;&lt;/div&gt;
      &lt;input type="range" class="slider"&gt;
      &lt;div id="addBtn"&gt;&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
