# Undesired new page with fullwidth, framebox, and enumerate

How can I prevent question 3 from being pushed to the third page here? What causes this anomalous behavior?

\documentclass{article}

\usepackage[margin=1in]{geometry}
\usepackage{fullwidth}
\usepackage{lipsum}

\begin{document}
\lipsum[1-5]
\begin{enumerate}
\item What is 1+1?
\item What is 2+1?
\item \lipsum[1]
\end{enumerate}
\end{document}

• Do you rely on fullwidth? Package exsheets provides a command that does what you want. en.wikibooks.org/wiki/LaTeX/Teacher%27s_Corner#Exsheets – Johannes_B Oct 8 '17 at 6:18
• Thanks @Johannes_B. I'm happy to get rid of fullwidth but exsheets seems overkill. – JPi Oct 8 '17 at 12:35
• To be clear: I want the box to be full width. And yes, I know I can jump out of enumerate' and resume using enumitem but since I could be three levels deep, this would be a serious pain. – JPi Oct 8 '17 at 14:07

Well, this works:

\documentclass{article}

\usepackage[margin=1in]{geometry}
\usepackage{enumitem}
\usepackage{lipsum}
\newcounter{indentlevel}
