- This is the behavior in every version I tried, and I reviewed the FAQ for entries about *everything and didn't find anything relevant*

### 💻 Code

```ts
export type GoodDocNode =
| string
| ["i", ...GoodDocNode[]]
| ["li", index: number, ...GoodDocNode[]];

export type BadDocNode1 =
| string
| ["i", ...tagged: BadDocNode1[]]
// ^^^^^^^^
| ["li", index: number, ...BadDocNode1[]];

export type BadDocNode2 =
| string
| ["i", ...BadDocNode2[]]
| ["li", index: number, ...tagged: BadDocNode2[]];
// ^^^^^^^^
```

### 🙁 Actual behavior

Error:
```
Type alias 'BadDocNode1' circularly references itself.
Type alias 'BadDocNode2' circularly references itself.
```

### 🙂 Expected behavior

No errors, because the only differences between the two is the name on the rest parameter in the tuple, nothing structurally is different.

### Additional information about the issue

_No response_

Utilisez le TypeScript Playground lié et la reproduction avec BadDocNode1/BadDocNode2 comme point de départ ; étudiez la vérification des alias de type circulaires pour les paramètres rest nommés de tuples. C’est terminé lorsque la reproduction ne produit aucune erreur de référence circulaire, tandis que l’exemple GoodDocNode structurellement équivalent reste valide.
