But does the user agent add any behaviors? Or does it simply
implement or not implement the behaviors specified by the author?

In the same vein, the user agent ultimately determines what the
user views, but the user agent doesn't just make up content.
I don't think it makes up behaviors either.

In this sense, active elements come from content.
