[Bug]: v8 Loading @emotion/react more than once warning

[jlin5]

Describe the bug

On Storybook v8, I get a warning from @emotion/react:

You are loading @emotion/react when it is already loaded. Running multiple instances may cause problems. This can happen if multiple versions are used, or if multiple builds of the same version are used.

I found a bug that reported a similar issue https://github.com/storybookjs/storybook/issues/25761 but it still happens.

To Reproduce

1. View https://stackblitz.com/edit/github-w7bhhe?file=src%2Fstories%2FButton.tsx
2. Check the logs

Having the same problem on distant server (reproduction). It renders fine locally (no bug).

Seeing this in the reproduction but not when I try to reproduce locally. 🤷
