In ShadyDOM mode, dom-repeat has some issues in stamping when it is distributed content, e.g.

<!-- x-outer template -->
    <template>
      <x-inner>
        <slot></slot>
      </x-inner>
    </template>

<!-- dom-repeat in x-outer -->
  <x-outer>
    <dom-repeat items='[{"name": "item0"}]'>
      <template>
        <div id$="[[item.name]]">{{item.name}}</div>
      </template>
    </dom-repeat>
  </x-outer>

The issue here is that the dom-repeat is getting patched by x-outer when it creates its shadowRoot and then un-patched when it upgrades. Since dom-repeat does not create a shadowRoot (the only way an element kicks off patching currently), it never gets re-patched.

This problem is similar to #62. Both of these issues are suggesting that the mechanism via which an element is patched is going to need some work.

Will be addressed via webcomponents/shadydom#7.
