Multi-line code blocks copied from browser have ^J (control J) instead of newlines

Problem

Multi-line code blocks copied from browser have ^J (control J) instead of newlines. This breaks the copy-pasting of multiple shell commands from docs into a terminal.

Steps

1. Create a code block like

   echo a
   echo b
   

2. Generate and view the site in a web browser (tested with safari and brave on mac)

3. Copy the two lines above

4. Paste into a terminal

Expected: two echo commands, that both run, printing a and b.

Actual: echo a^Jecho b is pasted, only the first echo command runs, only a is printed.

At the time of writing this can also be seen at this code block:
