[V3] Some imports fail inside of workers in a production build

[davidwallacejackson]

Describe the bug

I'm instantiating a web worker from the monaco-yaml library. In v2, nothing unusual happens when I do this. In v3 beta 6, dev works normally, but in a build, the build fails with this error:

[vite:worker] 'Schema' is not exported by node_modules/js-yaml/index.js, imported by node_modules/monaco-yaml/lib/esm/_deps/yaml-language-server/lib/esm/languageservice/utils/parseUtils.js
