So, we don't actually redefine the entire element, we just define a new template for ShadyDOM to play with. The actual code is here. I wouldn't reuse it verbatim, as it makes some assumptions that are very specific to us (like that, 99% of the time, our theme elements don't change their template once they've been stamped out the first time, so we don't need to worry about advanced diffing and such). We're also using a slightly older version of the polyfill, so it's possible that ShadyDOM has some new features that would get rid of some of this code.
