What tool are you using for code review? On my end it is formatted quite well (github and CLion), so it's hard to fix because I'm not really able to reproduce it.
Maybe we can just replace it with the link to the docs? This way we don't have to worry about formatting

I've changed it, I hope that it helps on you end, if not we can remove it and leave just the link
