Happy to get any help I can get.

The challenge right now is that we are missing a piece of plumbing -- the ability to forward child nodes of an element down the shadow DOM subtree. The equivalent bit in XBL2 is http://dev.w3.org/2006/xbl2/#the-content-element.

For example, I imagine we design our implementation like this:

details
   div::-webkit-summary-panel -- represents the panel in which summary is laid out.
      div::-webkit-details-indicator -- represents open/closed indicator of details
      summary
   * -- any other elements.

The divs in this tree will be in the shadow DOM. The summary, although rendered as child of the shadow DOM divs, is actually a direct child of details when viewed from DOM.

Implementing this plumbing will be the first step.
