-In the classic editor, the editor stylesheet is loaded directly into the iframe of the WYSIWYG editor, with no changes. Gutenberg, however, doesn't use iframes. To make sure your styles are applied only to the content of the editor, we automatically transform your editor styles by selectively rewriting or adjusting certain CSS selectors. This also allows Gutenberg to leverage your editor style in block variation previews.
