During inheritance, child components are not copied

[dthevenin]

Let use this specification:

<c id=c1 href=c2 />
<c id=c2>
  <c href=Button />
</c>

When this spec is rendered you have the following DOM witch is what you want:

<c1>
  <c2>
    <button />

But if you add a component into c1, ex:

<c id=c1 href=c2>
  <c href=List />
</c>
<c id=c2>
  <c href=Button />
</c>

You obtain this DOM that is not what you expect, because the button disappear:

<c1>
  <c2>
    <list />

The right DOM should be some thing like:

<c1>
  <c2>
    <button />
    <list />
