Should this be void instead of bool?

Yes, although this goes away given fs@'s comments below.

Can you put the above 4 functions (err, it will be 3) on SVGStyleElement?

I thought they might be here for sharing with SVGScriptElement, but it looks
like that would go through shared code with ScriptLoader.

Agreed - with the below twist.
Could we try using EventSender and Co. instead to converge (rather than diverge)
with HTMLStyleElement? The 'load' event crazies may have shaped the current
solution, but I don't think we should be basing "new" stuff on that structure.

Done.
