ltablex 导致内容超出页面底部边距

Question

因为某些原因，我需要使用tabularx来排版表格，并且需要能够跨页。所以我选择ltablex同时满足这两个需求。但是我发现tabularx使用 会导致环境附近的内容超出下边界ltablex。我该如何解决这个问题？是 固有的 bug 吗ltablex？或者如果我想让跨页的表格同时支持 X 列，还有其他解决方案吗？

\documentclass[a4paper]{article}
\usepackage[left=3cm,right=3cm,top=3cm,bottom=3cm,footskip=0cm,headsep=0cm,headheight=0cm,showframe,showcrop]{geometry}
\usepackage{tabularx}
\usepackage{ltablex}
\usepackage{graphicx}
\renewcommand{\topfraction}{.8}
\begin{document}
\begin{figure}
\centering
\includegraphics[height=17cm,width=10cm]{fig}
\caption{A}

考虑到@DavidCalisle 和部分@marv 注释，您的文档示例可以写成：

\documentclass[a4paper]{article}
\usepackage[margin=3cm, 
            showframe,showcrop]{geometry}
%\usepackage{tabularx}  it loaded by ltablex
\usepackage{ltablex}
\usepackage{tabularray}
\UseTblrLibrary{booktabs}
\usepackage{graphicx}
\renewcommand{\topfraction}{.8}

\usepackage{lipsum}

\begin{document}
    \begin{figure}
\centering
\includegraphics[height=16cm,width=10cm]{example-image-duck}
\caption{My lovely mr. Duck}
    \end{figure}
