Code outline: exportDefaultExpression outline could not show properly

[IWANABETHATGUY]

• I have searched through existing issues
• I have read through docs
• I have read FAQ

Info

• Platform: macOS
  but i am pretty sure you can reproduce this in other platform
• Vetur version: 0.24.0
• VS Code version: 1.44

Problem

this is not a bug for now , but may happen in next release

• VSCode Version:1.44.0
• Electron: 7.1.11
• Chrome: 78.0.3904.130
• Node.js: 12.8.1
• V8: 7.8.279.23-electron.0
• OS: Darwin x64 18.7.0

Steps to Reproduce:

1. use vscode inter typescript version which is 3.8.3
2. open a test.js file , and input code as below

export default {
  a: 'string',
  b: 2,
  c () {
    
  }
}

3. a exportExpression outline is looks like
   

when i change the typescript version to 3.7.5
the outline show below, i think this may be better, but i am not sure if this is a typescript bug or vscode's.

大纲 is outline

Does this issue occur when all extensions are disabled?: Yes

i make a issue to vscode, but there are thousands of issue in list, i am not sure they could notice me.

I contribute this repo yesterday, i clone the repo and install dependencies, the typescript version in directory server is ^3.7.5 but actually install 3.8.3, so when i vsce package it , i found that exportDefaultExpression outline gone, the same result as the first picture.

The exportDefaultExpression outline is import for .vue, because we can quickly jump to the component option like method, data with powerful symbol, but this change may destroy this experience. This may be a upstream bug of typescript , but i am not sure i can explain clearly about that, so i hope you could notice about this breaking change (not sure a bug or something else)

Do I need to manually install this version of typescript, or does the latest vscode install it?

If manual, how do I do that?

Sorry for dumb questions.

• Enable vetur.useWorkspaceDependencies and install the latest version of typescript in your project
  or
• Wait for the next release of Vetur.

This seems to not work for TypeScript enabled SFC with export default Vue.extend({options});. Is this a bug or am I doing something wrong with my SFC?

Vetur version: 0.28.0
Project TypeScript: 4.0.3
"vetur.useWorkspaceDependencies": true
