title: FormattedNumber in react-intl does not wrap currency to round bracket if it is negative in chrome
body: <p>When i use <code>FormattedNumber</code> from <code>react-intl</code> to format currency, it won't format negative currency amount to have parenthesis around the currency in chrome.</p>
  
  <p>It does work in Internet Explorer but does not work in Chrome and Mozilla Firefox.</p>
  
  <pre><code>&lt;FormattedNumber  
                          style='currency'
                          currency='USD'
                          minimumFractionDigits={2}
                          maximumFractionDigits={2}
                          value={-100.100}/&gt;
  </code></pre>
  
  <blockquote>
    <p>Output in IE -> ($100.10)</p>
    
    <p>Output in Chrome-> -$100.10</p>
  </blockquote>
  
  <p>Is there any option to get ($100.10) in Chrome/Firefox.</p>
