Monaco Editor Playground Code

Reproduction Steps

This PR appears to break applications that rely on importing editor.main.css, for example, to inject Monaco Editor's styles into a Shadow DOM.

https://github.com/microsoft/monaco-editor/pull/5155

In v0.55.1, I could still import editor.main.css. However, starting with v0.56.0, neither of the following imports works:

import "monaco-editor/min/vs/editor/editor.main.css"
import "monaco-editor/editor/editor.main.css"

Research direction

Start by reviewing PR #5155 and comparing the published package contents and import paths in Monaco Editor v0.55.1 and v0.56.0. Verify the two reported editor.main.css imports in a minimal application, then confirm that the supported CSS import works for applications injecting Monaco styles into a Shadow DOM.
