Today, backend generates stylesheet change event synchronously from within set* command. But CSSStyleModel defers its dispatching until the stylesheet content is available. This prevents us from ignoring update events from within commands that initiated those updates. This change makes stylesheet change event dispatch synchronously and delegates stylesheet content fetching to the event client.
