looks like this was addressed. cool.

Hey, sorry I never responded to this. I did see it but admittedly forgot to get back to you.
In short, yes, this is being rectified. The current implementation in master is changing and is considered unstable, though the tests pass. I'm currently exploring the best way to do this.
The long answer is that simply overriding prototypes doesn't seem to be a viable option. It would be the best option if Webkit didn't have this bug that prevents one from getting the native accessor implementations using getOwnPropertyDescriptor()
. Even if that would be possible, Webkit has a bug where you're not allowed to override built-in property descriptors.
Due to these bugs, you have to re-implement, from scratch, the behaviour of things like innerHTML
and manually keep track of childNodes
, parentNode
et al. Manually re-implementing innerHTML
is possible using DOMParser
, but that requires that you leave the HTMLBodyElement
prototype untouched because internally the DOMParser
implementation expects all native implementations to be intact in order for you to retrieve the parsed DOM content off the parser result. Basically, you have to modify all element constructors except for the body element.
This is all well and good until you realise that not all HTML elements have their own constructor and that some simply derive from HTMLElement
directly. This means that in order to do everything through prototype overrides, one must be able to override HTMLElement.prototype
. Due to the Webkit bugs, this simply isn't an option.
The solution, which I am elaborating on is using wrapper objects similar to the Polymer polyfill. Eventually we might be able to use a hybrid approach, but I anticipate that becoming very dirty, very quickly.
