White code block on dark Cosmonaut theme.

Hi, first thank a lot for your work. It is awesome and the Zenith theme works flawlessly.

But when trying out the Cosmonaut theme, I found that the Codeblock remain white in the background and some character cannot be seen.

Just want to let you know if you have time to fix in the future. For now I'm sticking with Zenith.

Again thank you very much.

Well actually using the Zenith theme and then revert the color with Dark Reader extension look really great.
