I'm working on resolving https://github.com/servo/servo/issues/8213 as per the spec online and feedback in the servo channel. Note that currently I cannot build (and thus test) my code, so this is a bit of a rough first draft. I'd still like feedback on my progress, and I hope that there is another way for my code to be tested.
