When setting style to a CSSStyleValue we need to convert it to a StyleValue. If we already have one, we might as well use it avoid the work of serialization and re-parsing. I realised I misunderstood what "constructed from a USVString" means, so I've adjusted based on that. It does raise a question on what the source USVString is if that string resulted in multiple CSSStyleValues being created - see the linked issue.
