The real issue is no one knows this and being informed of weird UI quirks by sporadic user messaging seems the wrong approach. Eg if you care so much should you not instead be requesting a software fix?
There is no software fix other than simple removal of functionality. You still want code blocks to not wrap(scroll) and you still want prose blocks to wrap. We already have solutions for both cases. For prose quote with "> ". Making posting guidelines won't stop people from using the wrong thing. "Sporadic user messaging" is all there's left.
