--- Comment #21 from Koji Ishii <kojiishi@gmail.com> ---
After further investigations and discussions with some folks, my current
conclusion is to use composed tree for all attributes that should inherit
across shadow tree boundaries, unless it hits too much performance concerns.

The list of such attributes are:
- dir
- draggable
- dropzone
- hidden
- lang/xml:lang
- spellcheck
- title

Notes:
- ARIA/role are already spec'ed to use composed tree
- tabindex/autofocus in in bug 25473

I'll go sending a PR to the spec, and look into the performance concerns more
in details.
