https://tex.stackexchange.com/landing/r/digest?cta=question&id=695327

There is some weird insertion and deletion of paragraph breaks in my boxes when using this combination of packages. 
\documentclass[justified, nofonts, notitlepage, openany, debug]{tufte-book} 
\... 
[tcolorbox] [multicolumn] [multicol] [tufte] [tufte-book]

}}} 
\makeatother
