Why do you use css for layout attributes here and class="layout..." in other
places?

[dzhioev (left Google), 2015/06/20 02:01:55]

I only do this for ":host".

For 0.5 it was like:
<polymer-element name="x-foo" horizontal layout>
</polymer-element>

In 1.0 I could have made something like this:
Polymer({
  is: 'x-foo',
  hostAttributes: {
    class: 'horizontal layout'
  }
});

and this will work for a simple case like:
<x-foo></x-foo>

However if we set "class" property for the element:
<x-foo class="my-x-foo"></x-foo>

its value completely replace the value set in |hostAttributes|.
