Description Hayato Ito 2011-06-28 02:26:39 PDT

Elements in a shadow root can be traversed by bug 61410, but elements in shadow content is not included in this traversal.

It would be nice that we can define a rule so that we can traverse 'elements in shadow root' and 'elements in shadow content' in a 'mixed' way.

My gut feeling is that we should follow the XBL-style tree flattening algorithm and then apply focus traversal over that. Thoughts?

Yeah, we need a flattened tree somehow. I made this bug depends on bug 64072.
Let me investigate how we should get a 'flattened' tree.

Per the spec focus navigation works over the flattened (“as-rendered” in spec language) tree.
