title: Emmet expand abbreviation doesn't work in Visual Studio Code with the attributes
body: <p>I am starting to use Visual Studio Code for my web projects and I cannot live without Emmet, but I have a problem when I try to expand the abbreviations in HTML tags with attributes.
  Just an example. If I write <code>html:5</code> and press TAB key it expands all the HTML5 template</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
  &lt;head&gt;
      &lt;meta charset="UTF-8"&gt;
      &lt;meta name="viewport" content="width=device-width, initial-scale=1.0"&gt;
      &lt;meta http-equiv="X-UA-Compatible" content="ie=edge"&gt;
      &lt;title&gt;Document&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>And writing tags with id and class, like <code>p#id.class</code>, it generates properly next piece of code</p>
  
  <pre><code>&lt;p id="id" class="class"&gt;&lt;/p&gt;
  </code></pre>
  
  <p>But when I want to expand same tag with other attributes inside of square brackets, it doesn't work. Just add a tab space in the code.</p>
  
  <pre><code>p[align="center"]
  </code></pre>
  
  <p>And same thing if I try to add text in the tag using curly brackets</p>
  
  <pre><code>p{Test}
  </code></pre>
  
  <p>Can you help me to know how to configure it, or if it is a problem with my software / extensions?</p>
  
  <p>Regards,</p>
