Re: [webcomponents] [Shadow]: Focus navigation in distributed content (#103)

Here's a similar issue filed for Chromium:
https://code.google.com/p/chromium/issues/detail?id=459858

Current TAB focus navigation is based on tree-of-trees based traversing and
there is no way to your `shadow node 1 -> content -> shadow node 2` work
even with tabindex (or further the new 'tabstop' I'm working on).

Re-defining the focus navigation order of shadow DOM in terms of composed tree
would be one solution to this, but then it breaks <summary><details> focusing
behavior, which is also a valid case of using shadow DOM.
