Well, this is useful! I recently built BLeak [0], an automatic memory leak debugger for the client-side of web apps, which consumes heap snapshots during the automatic leak debugging process.

I had to work around the DOM limitations of V8 heap snapshots by building a JavaScript 'mirror' of DOM state that I could examine in the snapshots [1]. Perhaps I'll be able to strip out that logic and rely on the improved snapshots!
