### 💻 Code

```ts
// Your code here
```

### 🙁 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?

从 TypeScript 服务器的 outline 模型开始，重现 issue 中的两个代码示例，并比较为解构返回值生成的条目与为命名变量生成的条目。追踪为什么在解构情况下会省略嵌套的 a、b 和 c 条目，并在两种形式都一致地公开这些条目时认为 issue 已完成。
