esm-sourcemaps-broken

Run with:

npm install

ESM_OPTIONS={'cjs':{'paths':true}} NODE_PATH=./ node --inspect -r esm main.js

Chrome Version 72.0.3626.121 (64-bit), npm -v 6.7.0, node -v v11.11.0

Problem:

Sourcemaps is not working and the code disappears when remote debugging

(function (exports, require, module, __filename, __dirname) { const _7c9‍=exports;__dirname=__filename=arguments=exports=module=require=void 0;return _7c9‍.r((function *(){"use strict";let test,http;_7c9‍.w("test.js",[["test",["test"],function(v){test=v}]]);_7c9‍.w("http",[["default",["http"],function(v){http=v}]]);yield;_7c9‍.s();
