Thanks a lot for doing this.

Alas, I cannot r+ it, but it's almost LGTM

I think that if elementValue is an empty handle, that would segfault

> WebCore/bindings/v8/custom/V8DOMStringMapCustom.cpp:108

you can use elementValue.As<v8::Object> too.  These .As methods are rarely met currently as they were added relatively recently, up to you if you'd like to switch to new API or not

cannot r+ means I am not a reviewer

r+, reiterating antonm's point about adding an isEmpty() check.
