Description

Describe the bug: I'm using my styles like these:

export default (theme) => ({
    root: {
        position: 'relative',
        display: 'inline-flex',
        alignItems: 'center',
        textAlign: 'center',
        background: theme.bgColor,
        fontWeight: ({weight}) => weight, // here is the problem
    },
});

And I'm getting this error on server-side (client is fine): Warning: [JSS] Rule is not linked. Missing sheet option "link: true". If I delete the dynamic value for fontWeight I will not get this error again. The problem not only in the warning itself, but also in the way how my styles will be applyed in production mode (they break styles in the styles where I'm using dynamic value and server sends me wrong styles after page reloading). P.S. I have tried using styles like this const useStyles = createUseStyles(styles, {link: true}); and it's still not working :(

Codesandbox link: I'm sorry, I have a problem with adding codesandbox.io with SSR and node.js console.

Research direction
Investigate the JSS source code, particularly the handling of dynamic style values during server side rendering. The error 'Rule is not linked. Missing sheet option "link: true"' suggests that the sheet option is not passed correctly when using dynamic values. Check the `createUseStyles` function and the SSR setup in the JSS repository. The issue has 24 comments, so review those for any suggested fixes or workarounds. Focus on the `jss/src/Jss.js` and `react jss/src` directories.
