Distributed slot fallback content from Document tree is not counted properly

Project Member Reported by kochi@chromium.org, Apr 27 2017 
When slot fallback content is distributed from Document tree
to a shadow tree, getting distributed content via
slot.assignedNodes({flatten: true}) should return the content
distributed from Document.

E.g. in Document
<div>
  <#shadow-root>
     <slot></slot>
  </#shadow-root>
  <slot>
    <div>Fallback content</div>
  </slot>
</div>

With the example http://jsbin.com/yiwaxaqexo/edit?html,js,console,output

Expectation for slot.assignedNodes() would return [<slot (in document)>],
and slot.assignedNodes({flatten: true}) would return [<div>Fallback content</div>].

Safari TP works as expected, Chrome returns empty array for the latter,
as of today (M58).

Could you write web platform tests?
If we find any interoperable issues between UAs, it would be nice to have a test for that.

The CL is ready but I'm waiting for upstream WPT to be imported.

With the recent spec change, slots in non-shadow tree no longer need
to treat fallback contents in the same way as slots in shadow tree.
