Bundling docs are incorrect and incomplete

1. Bundling using https://www.tiny.cloud/docs/tinymce/6/vite-es6-npm/, the lines

   import contentUiSkinCss from 'tinymce/skins/ui/oxide/content.js';
   import contentCss from 'tinymce/skins/content/default/content.js';

   don't work: Uncaught SyntaxError: The requested module 'http://localhost:5174/node_modules/.vite/deps/tinymce_skins_content_default_content__js.js?v=1dcb8b20' doesn't provide an export named: 'default'
2. When removing the from stuff from the imports like this:

   import 'tinymce/skins/ui/oxide/content.js';
   import 'tinymce/skins/content/default/content.js';

   the css gets applied to the whole webpage rather than only the editor, so the fonts change (body {font-family:sans-serif} from TinyMCE css). TinyMCE should edit the shadow root of its iframe and not my document root. Oh wait, it doesn't even generate an iframe when bundling it using Vite, it just makes a div? What's the cause of that?
3. https://www.tiny.cloud/docs/tinymce/6/webpack-es6-npm/ is incomplete
