In mounted, ctrl-click on method invocation not jumping to definition

<template>
  <div>test</div>
</template>

<script>
export default {
  name: 'my-test',
  mounted() {
    this.foo() // ctrl-click on foo, not working
  },
  methods: {
    foo() {
      console.info(`hello`)
    },
    bar() {
      this.foo() // ctrl-click on foo, jump to definition
    },
  },
}
</script>

<style lang="less" scoped></style>

jsconfig.json

I have a similar issue, except with Vue 2.7 and jumping from a method to another method's definition also doesn't work, unlike in OP's case.

I've created a simple repro repo by running npm create vue@^2 and then making the following changes:

I haven't installed @vue/runtime-dom as I have Vue 2.7 and according to the setup docs it's not needed. I mean, I did try it for good measure, but unsurprisingly it didn't change anything 😁

For vue 2.6 you should use vetur.

What about 2.7, is it expected to work when defining components with export default {...}? I'm trying to investigate it but I'm new to language servers, it might take a while.

I started by checking the vue-language-server process with Chromium debugger and didn't find anything there.

Now I'm doing the same with typescript-language-server and I'm currently in this file:

.../vue-language-server/node_modules/@vue/language-server/node_modules/@volar/typescript/lib/node/decorateLanguageService.js

It's in the Volar directory, but it comes up when debugging TS language server because this file uses it:

.../typescript-language-server/node_modules/typescript/lib/tsserver.js

It calls getDefinitionAndBoundSpan() which then calls linkedCodeFeatureWorker(), that's what I'm stepping through now, maybe I'll get to the bottom of this. Anything you can advise?

EDIT: the workaround from #4996 fixed the issue for me.
