Fwd: [dom] MutationObservers -- observing certain property changes

See http://lists.w3.org/Archives/Public/www-dom/2013JulSep/thread.html#msg94,
several threads spawned about MutationObservers.

In the end people decided it was a wontfix
https://www.w3.org/Bugs/Public/show_bug.cgi?id=23226 and all our hopes lie
in custom notifications + Object.observe
