preact/debug breaks on preact/devtools import

Reproduction

https://codesandbox.io/s/preactdebug-esm-7165v?file=/index.html

Steps to reproduce

Using the link above, you can see that nothing is rendered on the page.
The error message that I get is a 404 on https://unpkg.com/[email protected]/devtools?module.
I believe this is because of trying to use scope like naming without scoping. So preact/devtools instead of @preact/devtools. unpkg is picking this up as a path name instead and not reading from the package.json.

Expected Behavior

https://unpkg.com/preact/devtools should resolve to https://unpkg.com/[email protected]/devtools/dist/devtools.module.js?module

Actual Behavior

https://unpkg.com/preact/devtools resolves to https://unpkg.com/[email protected]/devtools?module

This is a known error in the module resolution code of unpkg. This can't be fixed on our end.

See:

• ?module currently generates wrong import mjackson/unpkg#281
• Use resolved versions instead of semvers when using ?module mjackson/unpkg#129
• Module resoultion in unpkg doesn't work. (Bug in unpkg) #2564

The recommended solution is to use a CDN which supports proper module resolution, like https://npm.reversehttp.com/

// preact and preact/hooks: 10.5.7, and htm/preact: 3.x.x:
import { html, render } from 'npm.reversehttp.com/[email protected],[email protected]/hooks,htm@3/preact';

Closing, because this is a duplicate of #2564 and we can't solve it on our end.
