[Bug] memoryFs not able to load dynamic chunks on node

[verydanny]

I'm not sure if this a memoryFs issue or how 'webpack-isomorphic-dev-middleware' uses require-from-string, but it loses context for dynamic chunks. I realize a lot of people use dynamic-import-node, but I need to split chunks on server and client for testing reasons. The client version works perfectly.

Example:

import React, { Component } from 'react'

import('components/home' /* webpackChunkName: "home" */ ).then(m => console.log(m))

export class App extends Component {
  render() {
    return (
      <div>
        Hello
      </div>
    )
  }
}

Error:

I dug into this yesterday, I don't believe this is possible unless a different in-memory filesystem is used, or node's Module._findPath is rewritten inside, specifically for memoryFs.
