I'm currently porting Luakit to the WebKit 2 API, and one thing giving me an inordinate amount of trouble is implementing a robust port of the scroll position indicator. Currently I'm monitoring DOMSubtreeModified events on a web extension and updating a UI-process cache of the document height over IPC, in an effort to keep the same synchronous API that Luakit provides to Lua scripts. This approach has a considerable performance cost and is also rather unreliable. I'd like the ability to monitor changes to document height; something like a "notify::scroll-height" signal on a WebKitDOMElement, as this was what I tried first.
