title: Angular 2: sanitizing HTML stripped some content with div id - this is bug or feature?
body: <p>I use <code>&lt;div [innerHTML]="body"&gt;&lt;/div&gt;</code> to pass unescaped HTML to my template, and when I pass to <code>body</code> <code>div</code> with attribute <code>id</code>, Angular throw:</p>
  
  <blockquote>
    <p>WARNING: sanitizing HTML stripped some content (see <a href="http://g.co/ng/security#xss" rel="noreferrer">http://g.co/ng/security#xss</a>).

  <p>So why it says this? What can be dangerous <code>id</code> in <code>div</code>? Could this bug?</p>
