Describe the bug
Dynamic data rendering with code block creates a flickering in the dom.

To Reproduce
Steps to reproduce the behavior:

1. Marked Demo

consider if the code block mentioned in the above link is inside a variable and the content is printing one by one. (you can reproduce this by typing a code block in this demo link) you can see a dom flickering issue because it is printing P tag first then after each new line it change to code block.

Expected behavior
It should work without any dom issue

Can you show a video of this behavior? I don't see it flickering.

I see the issue. Fenced code blocks currently require a newline at the end of the markdown if there are no closing ticks. This should be fixed by #2756
