VSCode intellisense is wrong on type of emit

[vidal7]

In Vue 2.7, options API (defineComponent), TS 5, Volar 1.6.1, type of event is wrong in VSCode

It should have been

'event-without-payload': ($event?: undefined) => void

Also, it would have been nice that Volar throw a typescript error on handleEventWithPayload in the template has handleEventWithPayload does not satisfy the type (a: number, b: boolean) => void has defined in the p-component-issue

emits: {
            'event-without-payload': (): void => { },
            'event-with-payload': (a: number, b: boolean) => { }
        }

For reproduction repo, you can take the same as the issue 2742 (https://github.com/vidal7/volar-issue-2742)

Duplicate of #1855

@johnsoncodehk , are you sure it is related to #1855 ? This issue does not involve that one of an event has an argument typed as any

[johnsoncodehk]

Yes it has nothing to do with any, it's about how Volar infers a specific type from multiple overloads. Can you post your use case in #1855?

Done here. #1855 (comment)

Thanks!
