Missing nodeKey when reactify

[fbjorn]

Hi,

I'm trying to import Svelte components in a React codebase, but I'm getting this error:

Uncaught TypeError: Cannot read properties of undefined (reading 'replace')
    at portalTag (svelte-preprocess-react.js?v=4fe1c300:334:44)
    at svelte-preprocess-react.js?v=4fe1c300:361:39
   <... rest of traceback ...>

I've checked the sources and apparently nodeKey is undefined inside the portalTag function, thus it fails.

I've also created a minimal reproducible repository for you to help with the investigation: https://github.com/fbjorn/svelte-react-issue-demo

Just pnpm install && pnpm dev to see the error

Looking forward to hear your feedback on this, thanks.

update: downgrading your lib to 2.0.4 solves the problem
