### 🕗 Version & Regression Information

- This is the behavior in every version I tried (v5.8.3 - Nightly)

### 💻 Code

```ts
// @filename: foo.impl.js
/**
* @import { Foo } from "./foo.js"
*/

/**
* @returns { Foo }
*/
export function alloc() {
return {
prop1: 42,
prop2: "lorem ipsum"
}
}

// @filename: foo.js
export * as Foo from "./foo.impl.js"
/**
* @typedef Foo
* @prop { number } prop1
* @prop { string } prop2
*/

// @filename: index.js
import { Foo } from "./foo.js"
// ^^^ 'Foo' is a type and cannot be imported in JavaScript files. Use 'import("./foo.js").Foo' in a JSDoc type annotation.ts(18042)

const foo = Foo.alloc();
```

### 🙁 Actual behavior

tsc/lsp emmits error

### 🙂 Expected behavior

no error

### Additional information about the issue

same example works fine using ts files

Reproduce the example using foo.impl.js, foo.js, and index.js with tsc or the language service, then trace the diagnostic for the import of Foo and compare it with the working TypeScript-file case. Done means the JavaScript example reports no import error and Foo.alloc() remains usable.
