This collection has some pretty strange behaviour, particularly with the IsHTMLDDA slot which is defined in the javascript spec specifically for this object. This commit implements pretty much all of this interface, besides from the custom [[Call]]. There is also no caching over this collection. Since it is a live collection over the entire document, the performance is never going to be great, and I am not convinced any speedup for this legacy interface is worth a massive cache.
