Unable to use new decorators in vue with vite and babel

[svihpinc]

Vue version

3.3.8

Link to minimal reproduction

https://stackblitz.com/edit/vitejs-vite-cbe6hz

Steps to reproduce

Build the given reproduction using npm run build and see this error:

error during build:
Error: [vue/compiler-sfc] Cannot use the decorators and decorators-legacy plugin together

Even though in vite.config.ts, the vue plugin's config lists the decorators babel plugin, it is not being considered in the following code.

vue({
  script: {
    babelParserPlugins: ['decorators'],
  },
}),

The following code seems to be the cause of it: https://github.com/vuejs/core/blob/main/packages/compiler-sfc/src/script/context.ts#L167.
Since it is never checked if user has passed the decorators plugin before adding the decorators-legacy one, both the plugins end up being pushed in the array

What is expected?

no error on build

What is actually happening?

Error on build

Any additional comments?

It seems like the plugins array check to see if it includes 'decorators' is a mistake, since that will always come out to be true. It should check in the userPlugins array instead

How would I know which version this fix will be released in?
