Vetur cannot find variables/methods when used inside an anonymous function for an event

[aziztitu]

• I have searched through existing issues
• I have read through docs
• I have read FAQ
• I have tried restarting VS Code or running Vetur: Restart VLS

Info

• Platform: macOS
• Vetur version: 0.33.1
• VS Code version: 1.54

Problem

Vetur is not able to find symbols when used inside an anonymous function for an event like so:

<v-btn
  color="primary"
  depressed
  @click="
    () => {
      if (!resetPasswordSessionId) {
        sendResetPasswordEmail();   // I get an error here: "Cannot find name 'sendResetPasswordEmail'"
      } else {
        resetPassword();   // I get an error here: "Cannot find name 'resetPassword'"
      }
    }
  "
  :loading="forgotCredentialsSendingEmail || resettingPassword"
  >Submit</v-btn
>

Error message:

Cannot find name 'sendResetPasswordEmail'
Cannot find name 'resetPassword'

Reproducible Case

• Just use an anonymous function inside the template
• Try to reference a state/prop inside this anonymous function
• Vetur throws error similar to the ones mentioned above

Same issue. It is especially bad if a component uses @emit from vue-property-decorator, as any non-default type will cause similar errors
