### 💻 Code

```ts
/**

	subscribe(): Observable<X>
};

	CLICK = "click",

type CPUnmappedEvents = {
	[K in Exclude<CPEvents, keyof CPMappedEvents>]: Event;

export type CPEventsMap = CPMappedEvents & CPUnmappedEvents;

```

### 🙁 Actual behavior

Intellisense (autocomplete) suggests two different subset of valid values when accessing a mapped object through dotted access and indexed access, but accessing with a dotted access to an unsuggested (available in indexed access and there fore still valid) property seems to be still valid and well-recognized.

### 🙂 Expected behavior

The suggested values should be the same if there is not a specific indexed signature.
