Describe the Bug

Not sure if I'm missing something or if this issue would be better suited for the Expressive Code repo, but using the Code component when expressiveCode.emitExternalStylesheet is set to false breaks its styling completely.

Oddly enough, the issue seems to go away when you also include any Markdown/MDX code block on the page.
