AI Assistant Code Blocks: Unreadable in light theme colour

this is what I see when the Assistant recommends code changes. I don't think I have any special theme going - just using the blue background which is your theme. I have to highlight the recommended changes to see it.

This is a confirmed issue; current workaround is to use a dark mode theme as the issue does not appear there
