unable to use Polymer's dom mutation observer polyfill with mutation summary library

[veryhim]

Functionality - replicate entire page using DOM mutation observer. This works well in chrome/ FF. For IE9, I am trying to use dom mutation observer polyfill of Polymer framework to make mutation_summary.js, tree_mirror.js work. Mutation_summary expects a MutationObserver implementation from browser/ polyfill but it remains undefined when tree_mirror tries to initialize dom.

Question: Is it possible to use the mutation observer polyfill independently w/o setting up Polymer first or w/o specifying polymer's HTML elements in the webpage. And, can it work with mutation_summary and tree_mirror implementations.

The https://github.com/Polymer/MutationObservers polyfill works stand alone. There are tests in that repo that works.

Notice that mutation events in IE and Chrome/Safari are not very reliable so I doubt they would be good enough to mirror a page.

thanks.

Polyfill (independently) provided the required Mutation Observer functionality in IE9 and thus helped in replicating/updating the page.
It works great; just that setting/using 'global' (done with global.MutationObserver) caused problem. Had to handle it separately (reason could be in my application somewhere or how it is picked in my environment by other libraries).

Would you mind providing some more details? Can you post a jsbin?

Veryhim - I have similar requirement to use polymer version of MutationOberserver with mutation-summary/tree-mirror for IE9 and IE10, were you able to get success with this? If possible can you share your experience/code?
