[Alexander Pavlov (apavlov)]

A UTF-8 BOM is not handled properly by the CSSParser (and it should never get through to it).

Can we be sure that the styles content is already loaded at this point?

Yes, all external stylesheets will have been loaded by the time window.onload fires.

You should instead fetch CachedResource, cast it to the Stylesheet and get decoded data.
