data-view-id being rendered in tag closing

[scorphus]

The scanner wrongly adds data-view-id='X' to a tag close </TAGNAME>.

In EJS, for example, if you have:

<textarea>
  <select>
    <% can.each(this.items, function(item) { %>
      <option <%= (el) -> el.data('item', item) %>>
        <%= item.title %>
      </option>
    <% }) %>
  </select>
<textarea>

it gets wrongly rendered:

<textarea>
  <select>

      <option  data-view-id='3'>
        One
      </option>

      <option  data-view-id='4'>
        Two
      </option>

  </select data-view-id='5'>
</textarea>

It goes the same with Mustache. The bug can be seen in this fiddle. And the fix is available in this fiddle.

I've made use of valid HTML in test cases, pull request description and fiddles. Just to make it right.
