Incorrect rendering of triple-back-tick code blocks

[PerMildner]

In 1.4 (and earlier), if the chat bot answers with code formatted using triple back-ticks, everything looks fine until the closing back ticks, at which time the output becomes a single unreadable line.

E.g. ask Llama 3.3 "Show me a simple hello world C program", the answer will start with (I have delimited it with BEGIN and END):
BEGIN
Hello World in C

#include <stdio.h>

int main() {
    printf("Hello, World!\n");
    return 0;
}

END

but the chat will show as in the screen dump
