Hi everyone,

I’ve noticed a minor but annoying bug when there’s a code block inside a Markdown code block, like the image below:

 ![bug-evidence](https://us1.discourse-cdn.com/openai1/original/4X/6/5/3/6532132f4e9b1fa4265644f00acfe0e773174204.png)

It seems that this forum’s message system also has this nested markdown code block formatting bug 😅 😅

But you can replicate it by using the prompt in the image.

Additionally, the UI for code blocks in user messages could use some love—it feels a bit clunky at the moment. Could this be looked into?

Thanks for your help!

github handles this correctly with indentated nested blocks.

chatgpt now dos it too:
