externalsType.promise are not awaited in bundled dependencies

[roblan]

Bug report

What is the current behavior? Externals of type 'promise' are passed as promise (not as awaited value) to bundled amd type dependencies.

If the current behavior is a bug, please provide the steps to reproduce.

src/index.js

import internalValue from 'greetings';
import depValue from './dep.js';

console.log(internalValue, depValue);
alert(internalValue === depValue);

src/dep.js

define(['greetings'], (dep) => dep);

webpack.config.js

module.exports = {
    mode: 'development',
    externals: (ctx, callback) => {
        if (ctx.request === 'greetings') {
            callback(null, `Promise.resolve('Hello there!');`, 'promise');
        } else {
            callback();
        }
    },
};

What is the expected behavior?

Promise type externals are passed to bundled dependencies as awaited value
