💻 Code

import * as OctokitTypes from '@octokit/core/types';

🙁 Actual behavior

Behavior 1:

Type of the following variable is recognized as any:

import { Octokit } from 'octokit';
export type T = typeof Octokit;

Behavior 2:

Type of the following variable is recognized as any;

import * as OctokitTypes from '@octokit/core/types';
export const OctokitTypes;

Behavior 3: Even stranger behavior

In the following code snippet:

import * as OctokitTypes from '@octokit/core/types';

1. Remove any character from package name @octokit/core/types (e.g. @octokit/core/type), TS error occured, which is expected
   
2. Re-add the removed character, TS error remained, which is very weird
   
   Apparently there is some problem with the language server, as the package name has been changed to */types, but it still reports error of */type

🙂 Expected behavior

N/A

Additional information about the issue

No response

Start by reproducing the three behaviors in the linked TypeScript Playground, focusing on the @octokit/core/types import and the stale diagnostic after editing the package name. Trace the relevant module-resolution or language-server behavior; done means the valid import is resolved with its actual types and diagnostics update after the edit.
