### 💻 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?

Beginne mit dem Outline-Modell des TypeScript-Servers und reproduziere die beiden Codebeispiele aus dem Issue. Vergleiche dabei die für eine destrukturierte Rückgabe erzeugten Einträge mit denen für eine benannte Variable. Verfolge, warum die verschachtelten Einträge a, b und c im destrukturierten Fall fehlen, und betrachte das Issue als erledigt, wenn beide Formen diese Einträge konsistent offenlegen.
