The site editor, unlike other editors, generates the styles coming from global styles (presets, styles) dynamically in the client. This is because the user can modify any value that we need to consolidate (merge core, theme, and user style preferences). We don't want to have the global styles twice, as it introduces subtle bugs. Props oandregal, youknowriad. See #55567. Built from https://develop.svn.wordpress.org/trunk@53208 git-svn-id: http://core.svn.wordpress.org/trunk@52797 1a063a9b-81f0-0310-95a4-ce76da25c4cd
