Context does not work with SSR

[efoken]

Describe the bug
When using createContext, SSR is broken for me. I'm getting this errors in the console when starting Next.js:

ReferenceError: CustomEvent is not defined
     at dispatchEvent (file:///Users/eike.foken/Code/test-ui/node_modules/.pnpm/atomico@1.65.0/node_modules/atomico/src/element/set-prototype.js:95:50)

     at useTheme (webpack-internal:///../packages/styles/src/theme/theme-provider.ts:19:68)

And also later on (if I polyfill CustomEvent with an empty function):

TypeError: node.dispatchEvent is not a function

Expected behavior
No errors in console

*SSR/SSG environment (Optional, required if the problem is caused by using SSR/SSG, please complete the following information):

• Environment version: node@18.10.0
• Framework: Next.js 12.2.6
