### 💻 Code

### 🙁 Actual behavior

Essentially for the code:

```
export const [var1, var2] = processLightDarkTokens({
a : {
b : {

}
},
c : {

}
});
```

The outline model returned by TypeScript does not show a, b and c. But for:

```
export const abc = processLightDarkTokens({
a : {
b : {

}
},
c : {

}
});
```

It does.

### 🙂 Expected behavior

I would expect a, b, and c to be visible in the outline model in both cases.

### Additional information about the issue

Hi, I am a developer on the VS Code team, and I recently received the following bug : https://github.com/microsoft/vscode/issues/241563. The bug is that the VS Code editor sticky scroll does not display the expected sticky lines. This happens because the outline model returned by the TypeScript server changes unexpectedly depending on if the function return variable is destructured or not. I attach a screen recording here to show the issue.

Essentially for the code:

```
export const [var1, var2] = processLightDarkTokens({
a : {
b : {

}
},
c : {

}
});
```

The outline does not show a, b and c. But for:

```
export const abc = processLightDarkTokens({
a : {
b : {

}
},
c : {

}
});
```

It does. Is this expected?

Commencez par le modèle d’outline du serveur TypeScript et reproduisez les deux exemples de code de l’issue, en comparant les entrées produites pour un retour déstructuré avec celles produites pour une variable nommée. Suivez la raison pour laquelle les entrées imbriquées a, b et c sont omises dans le cas déstructuré, et considérez l’issue comme terminée lorsque les deux formes exposent ces entrées de manière cohérente.
