Don't support submodule

[ParadeTo]

I have a node.importmap as follows:

{
  "imports": {
    "react-dom": "https://esm.sh/[email protected]"
  }
}

Here is a file to test:

import ReactDOM from 'react-dom'
import ReactDOMServer from 'react-dom/server.js'

The second line can't work.

Hi, I'm trying this package to load some remote modules (https) but not working. So I'm wondering Is there any configs that README don't point out?
BTW, I have debugged the source code and got some local paths in resolveSpecifier method.(etc: /username/project/xxx)
Thank you.
