Using global type in module file

[Ericlm]

Describe the bug

I'm using auto-imports in a Vue project, and while it works perfectly in vue components, I'm having issues with types in .ts files (like composables or stores).

• In .ts file without import/export, the Ref (or other types) are unknown, but the ref() etc. functions are not reported.
• It works only when using globalThis (globalThis.Ref)

It works when using a syntax like:

declare global {
  type Ref<T> = import('vue').Ref<T>
}

instead of export type {} inside of declare global {}.

Maybe this syntax should be used instead of export type {}. ?
