mdframed 环境的标题框中的定理陈述？

Question

我已经使用包定义了一个定理环境mdframed。但是，我希望将陈述包含在与包含证明的框不同的框中。

理想情况下，这应该是标题框。但是，如果我尝试在其中放置多行文本，文本只会水平放置，甚至忽略\\。

我在软件包文档和网上搜索了示例，但没有找到符合我要求的示例。有人知道是否可以做这样的事情吗？

我在这里提供了我当前环境的最小工作示例：

\documentclass[11pt]{book}
\usepackage{amsthm}
\usepackage[utf8]{inputenc}
\usepackage[usenames,dvipsnames,table]{xcolor}
\usepackage{tikz}
\usepackage[framemethod=TikZ]{mdframed}
\mdfsetup{skipabove=\topskip,skipbelow=\topskip}

大多数tcolorbox请求都可以立即完成。minipage boxed title=0.8\linewidth例如，最重要的是。
