In a JS file, using module.exports in a file changes the type of module from NodeModule to typeof import("...")

Bug Report

When using a JS file with @types/node, the type of module changes from NodeModule to something strange (typeof import("/sandbox/not_working");) after including a line like module.exports = {}.

🕗 Version & Regression Information

• This is the behavior in every version I tried, and I reviewed the FAQ for entries about 4.2.3

💻 Code

/// <reference types="node"/>
// INFO: This is JS

/**
 * @param {NodeModule} aModule
 */
function createLogger(aModule) {}

createLogger(module); // INFO: module here is triggering the error.

// INFO: THIS LINE BREAKS IT
module.exports = {};

🙁 Actual behavior

var module: {
    "\"/sandbox/not_working\"": typeof import("/sandbox/not_working");
}

Argument of type '{ "\"/sandbox/not_working\"": typeof import("/sandbox/not_working"); }'
is not assignable to parameter of type 'NodeModule'.

  Type '{ "\"/sandbox/not_working\"": typeof import("/sandbox/not_working"); }'
  is missing the following properties from type 'NodeModule': require, id, filename, loaded, and 3 more.

ts(2345)

🙂 Expected behavior

I expected module to always be of type NodeModule.

从 CodeSandbox 示例及其 not_working.js 复现入手，重点关注 module.exports = {} 如何改变 module 的推断类型。确认预期的 NodeModule 行为，并添加一个回归测试，展示 createLogger(module) 在导出赋值后仍然有效。
