In lining CSS breaks styles.

Hi, trying to use this amazing tool in a project. It works well for the most part but I have a few pages with embedded videos using https://astro-embed.netlify.app/components/youtube/ when I build and deploy the project the styles on the videos seem to get broken. https://stackblitz.com/edit/withastro-astro-wsnvzt <-- example here. To reproduce run `npm run dev` = styles are okay. `npm run preview` (with the inlined css) = styles are broken.
