[ERROR] Versions from 4.0.9 to 4.0.15 don't work on Codepen as ESM with ImportMaps

[angelhdzmultimedia]

Version

4.0.15

Reproduction link

codepen.io

Steps to reproduce

1. Create a vue@next codepen
2. Imported vue as ESM with ImportMaps successfully.
3. Tried the same with Vue router.
4. Got error "Uncaught TypeError: Failed to resolve module specifier "@vue/devtools-api". Relative references must start with either "/", "./", or "../"."

What is expected?

Importing VueRouter as ESM with importMaps succesfully, the same way it went with vue@next.

What is actually happening?

Error Uncaught TypeError: Failed to resolve module specifier "@vue/devtools-api". Relative references must start with either "/", "./", or "../". on versions from 4.0.7 to 4.0.15.

Only version 4.0.6 seems to work.

Update

I assumed it worked on version 4.0.6 because the error didn't happen and the createRouter function was output in the console.log, but the <router-view> is empty and this is printed in the browser's console:
