Font Awesome icons have text-decoration issues inside links
<p>I have a "ugly" issue with font-awesome, when I place a icon-link (icon inside a link) in front of a text. By hovering the icon, the icon itself will not get underlined but somehow the space between the text and the icon.
Somehow the text-decoration css rule from the link (underline while hover) collides with the one coming from the icon in this strangely appearing space.</p>

<p>How can I get rid of this underline in the space and have no decoration at all in the end?
(when possible without adding a class to the link element nor using JS)</p>

<p>Here is a code snippet that may help you.</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-css lang-css prettyprint-override"><code>a {
  text-decoration: none;
}
a:hover {
  text-decoration: underline;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css" rel="stylesheet"/&gt;
&lt;h1&gt;
  &lt;a href="#"&gt;
    &lt;i class="fa fa-wrench"&gt;&lt;/i&gt;
  &lt;/a&gt;
  Text of Title
&lt;/h1&gt;</code></pre>
</div>
