[dom] MutationObserver and createShadowRoot() (#170)

I'm looking for a way to keep track of ShadowRoots being created. Neither does the current implementation of ShadowDOM/MutationObserver in Firefox 44 and Chrome 48 register a mutation for `element.createShadowRoot()`, nor does either specification mention this situation specifically.

To the best of my knowledge it is currently not possible to get identified when a ShadowRoot is created for an element.

Has this ever been discussed and decided to be ignored, or has this just not come up before?
