Set caret position in a content editable element
<p>I'd like to set caret position in a content editable element but it seem's not working.</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var el = document.getElementsByTagName('div')[0];
var range = document.createRange();
var sel = window.getSelection();
range.setStart(el, 2);
range.collapse(true);
sel.removeAllRanges();
sel.addRange(range);
el.focus();</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div contenteditable&gt;Hi ! How are you doing ?&lt;/div&gt;</code></pre>
</div>
</div>
</p>
