Code to test

Simplified from got typings.

interface T {
    <T>(input: { type: 'text' })
    <T>(input: { type: 'json' })
    <T>(input: { type: 'buffer' })
}

declare const func: T

func({ type: /**/ })

No all literal or in-string completions, but okay if remove <T> from each overload.

🙁 Actual behavior

Completions in func({ type: '|' }) (text) missing completions from func2('|') (text, json, buffer)

🙂 Expected behavior

Completions for func({ type: '|' }) are the same as for func2('|')

I'm not sure probably its related to https://github.com/microsoft/TypeScript/issues/51047 (or duplicate)

Research direction

Reproduce the issue in the linked TypeScript Playground using the provided overload example, then compare completions inside the object literal with completions for the direct literal argument. Done means the object-literal expression offers the same text, json, and buffer completions as the direct call.
