[v9.0.0-rc.2] Event props in useSprings props function are not saved for future updates

[aleclarson]

In v9-beta.34, I could pass onFrame to useSpring like this

const [props, set] = useSprings(pages.length, i => ({
    x: i * window.innerWidth,
    scale: 1,
    display: 'block',
    onFrame: f => console.log(f),
    onRest: f => console.log(f)
}))

I've updated onFrame -> onChanged, but neither onChange or onRest seem to get called

const [props, set] = useSprings(pages.length, i => ({
    x: i * window.innerWidth,
    scale: 1,
    display: 'block',
    onChange: f => console.log(f),
    onRest: f => console.log(f)
}))

I don't have a demo for this, but I've noticed the same behavior in the useSpring hook

Fixed in 9.0.0-rc.3
