Ah, you're right, CodeMirror 6 appears to be more accessible. However it still only shows one line at a time. So that's still worse than Monaco. Monaco can show one or two hundred lines at a time. So with CodeMirror 6 I still would have to read text line by line without any way to skip a function for example, which is unnecesarily tedious. Sure, I understand that people don't have infinite time to spend on perfect accessibility. I was careful not to have any blaming tone in my message.
