Issue: [Bug]: Incompatibility between storybook and vue devtools...?
Labels: bug,vue3

### Describe the bug

I am getting a strange error in the console when trying to configure Storybook to use Pinia within a Vue & Vite project....

I have a simple reproduction case at https://github.com/eric-g-97477-vue/dev-tools-plugin-test

Either I have missed something in the configuration or there is a bug in either storybook or the vue devtools. I am not sure which is the case between those three options.

### Reproduction steps

To create this, I did the following...

(1) I created the default vue Project
```
$ npm create vue@latest                                                                                                                                                                                                                                     10:25:02

> npx
> create-vue

Scaffolding project in /Users/eric.g/depot/vue/devtools_test...

Done. Now run:

  cd devtools_test
  npm install
  npm run dev
```
  
(2) I initialized the project with `npm install`.

(3) I ran `npx storybook@latest init`

(4) I then setup storybook to be able to use Pinia. Based on https://storybook.js.org/docs/get-started/frameworks/vue3-vite, I added

```
import { setup, type Preview } from '@storybook/vue3';
import { createPinia } from 'pinia';
 
setup((app) => {
    app.use(createPinia());
});
```

to `.storybook/preview.js`.

(5) I then run `npm run storybook` and the below error appears in the console when I click around using the stories for button, header, or page.

```
