Servo is already hooked up to a (very old) version of SpiderMonkey, but it's missing enough DOM features that most pages hit errors. This Steam page hits "ele.canPlayType is not a function", "document.write is not a function", and "link.href is undefined".

Last I heard, Servo does not plan to support plugins such as Flash. I'm not sure if the existence of Shumway changes this.

Fun times ahead if document.write isn't already supported. When I rewrote Gecko's HTML parsing, accommodating document.write was a (or maybe the) dominant design issue.

I'm quite curious, why document.write is so hard to implement compared to other methods ? Is it not working a bit like innerHTML ?

We're actively working on document.write and as far as I know have future-proofed the design so that adding it won't involve massive rewrites.
