This was used to allow clients to pass ref and key
to createElement, which is no longer necessary due to intersection
types. If you need to declare a props object before passing it to
createElement or a factory, use ClassAttributes<T>:
var b: Button | null;
var props: ButtonProps & ClassAttributes<Button> = {
ref: b => button = b, // ok!
label: "I'm a Button"
};
