Nit: GetSecurityStyleForWebContents()?  Otherwise it sounds like it fetches the
window's current style or something.

Can this be const?  (I'd love for it to be static, but unfortunately you can't
have static virtual methods.)

Apparently not. :-/

You const-qualified the wrong thing :).  I was suggesting const-qualifying the
function, not the return type.
