💻 Code

enum MyEnum {
    FOO,
    BAR,
}

const foo: Record<MyEnum, string> = {
    // try to complete keys in this object
    // expected [MyEnum.FOO], [MyEnum.BAR]
    // actual "0", "1"
}

🙁 Actual behavior

"0" and "1" are suggested as completions

🙂 Expected behavior

[MyEnum.FOO] and [MyEnum.BAR] are suggested as completions

Additional information about the issue

using the quick fix Add Missing Properties uses the correct, expected behaviour

リンクされた TypeScript Playground を使って、Record<MyEnum, string> オブジェクトの補完を再現し、Add Missing Properties クイックフィックスと比較してください。enum をキーとするオブジェクトリテラルの補完動作を追跡します。[MyEnum.FOO] と [MyEnum.BAR] が "0" と "1" ではなく補完候補として提示されれば完了です。
