paper-dialog reparenting when 'layered=true'

[andy...@google.com]

When layered=true in paper-dialog, it is reparented to a layer higher in the DOM, and can no longer be styled using the rules defined within it's parents shadow DOM.

I know I can work around this by:

  - Using global styling rules

  - Creating a custom Polymer element that defines my style

But both of these solutions are not great. Are there any plans to allow 'regular' styling to work here?

I realize this may be a hard issue, but it seems like a big inconsistency when using Polymer with shadow DOM.
