Edited the file so that the loopProtect code, which is in the head of
the iframe on www.freecodecamp.org, is in the same script tag as the
base challenge content that get's rendered to the page. While the
loopProtect code is not rendered to the page like the rest of the
challenge code, it's within the same scope and seems to function
normally.
BREAKING CHANGE: None that I know of, but will keep checking.
Closes#16260
