Changing dynamic jss value

[janhoeck]

Hello,

I want to change a value of a jss property, when a prop changes. I read this article: https://github.com/cssinjs/react-jss#dynamic-values but this won't work, as you can see in my sandbox example https://codesandbox.io/s/4qy85qrly4

Maybe anyone could help me :D Why I want to change the property of a jss key: Because I want to animate it with a transition

Also, we have been documenting the use case in https://material-ui.com/customization/overrides/#2-dynamic-variation-for-a-one-time-situation.
